I married for love and i have a child. But now, my husband has a relationship with another girl. Because of this problems arose in my family. If I ask my husband about that, he says "I will not withhold provision for you and your child." 
Please give me a solution for my trouble.

Allow me to paint you a picture of how God works in our life. 
The rain has disappeared and the weather is calm and sunny, its September; time to plough and fertilize the land for the cultivation of grapes. After the land is prepared, the seed is sown and watered every day. The gardener waits for weeks to see it sprout. The healthy seeds start to sprout and the gardener trains the vines to climb by keeping a rod aside. In the first year of its growth, he concentrates on the formation of the stems rather than the fruit. He knows that, as the vine is young, it can’t produce mature and tasty fruits yet.

The older vine will thicken and transform into stems and branches. It will be the main support for the grapes in the following year. Apart from the stem, the vines will be pruned after the season, so that fresh and healthy vines will sprout in the coming season.

The gardener over here is the Father who is in heaven. When the Gardener prunes the plant, is it enjoyable for it? No, it’s always painful. Just like that when He prunes us it will be painful for our heart. He will cut down the unwanted things from our life, for us to be fruitful in the coming days. 

Fast and Pray 

Think of your current situation as your pruning period and what you have to do is - Fast and pray at the feet of the Lord for your husband. Then God will turn your problem upside down.

God says in John 15:5, “Without Me, you can do nothing.” Don’t share your worries with people who can do nothing, except gossip about it. But when you pour out all your problems before God in secret, He will mend the heart of your husband. 

My mother has undergone a tough time when my father was not a believer in God. For his heart to change, she prayed without telling anyone. God heard her prayer and changed my father's life and blessed her children. We are also blessed because of her prayer. 

Pray with Fait

A Canaanite woman came to Jesus and cried out, “Lord, Son of David, have mercy on me! My daughter is demon-possessed and suffering terribly.” Jesus replied to her saying, “It is not right to take the children’s bread and toss it to the dogs.” But she said, “Even the dogs eat the crumbs that fall from their master’s table.” And according to her faith, He said, “Woman, you have great faith! Your request is granted” and her daughter was healed at that moment. In the same way, God expects great faith from us and when we have faith in God, He will give us everything.

Once a woman came to me for prayer and said, “I am married and have a son. But now my husband has a relationship with our housekeeper. I know that he is a good person and I don’t know how he got into this trap. I love my husband very much and I want him back.” I prayed for them and the Lord changed his heart and now they are living happily.

When we cry and pray to God for our family and surrender them in God's hands, He will listen to our prayers. God will surely bring a change in their lives. When you believe, the Lord will give you peace and joy. Trust the Lord, He will help you. 

Be happy in the Lord 

It is difficult to be happy in the midst of sorrow but St.Paul, when he was in prison and in the midst of agony, writes, “Rejoice always” (1 Thessalonians 5:16). The Bible says in 1 Peter 1:8, “You rejoice with joy inexpressible and full of glory.” When we go through problems our hearts are broken but then when we allow God to come into us, He will fill us with His joy. 

"A shoe company designed a shoe after 16 years of research. They set a special spring for the shoe. They arranged four springs in the heels which were made by thick foam. When you walk, that spring would add a jump in your step. So they called many youngsters to wear that shoe for a trial and testing. What they observed was, when they ran with that shoe on, their faces were full of joy because when they tried to jump lightly, it makes them jump higher.” In the same way, the Lord has given us the Holy Spirit. When we struggle to do something, the Holy Spirit comes up to us and does what we cannot do and gives us joy and success in whatever we do. 

Wait upon the Lord 

Once there was a contest in the newspaper. The question asked was, “If you get an opportunity to draw a picture of the most beautiful woman in your life, whose picture will you draw?” The contest winner wrote the following answer, “For every person, their wife is the most beautiful woman in the world.” Wow! What a thought but how can it be? Everyone can’t be “fair” in their complexion, right? In family life, how a woman looks physically should not be a priority. But what matters is the wisdom of God which heals the wound of a heart, encourages and consoles a person when she opens her mouth. If it is so, her partner will not go to anyone else for comfort other than her. That’s how the wife becomes the most beautiful person in her husband’s life.

God wishes for us to have a happy family life and so, He will help you to get your husband’s love completely back to you by providing His divine wisdom to lead the family.

Just like how the grapevine bears fruit in its season, the Lord will dwell in your house and bring back what you have lost, in His time. He will help you to harvest joy in your family when you wait upon the Lord with faith. He is the only one who is worthy to be trusted. 

Come! Join with me and pray.

Dear heavenly Father, thank you for giving me a chance to read this portion. Lord help me to fast and pray at your feet to turn my beloved people’s hearts unto you. Help me to be happy in the midst of my sorrows just like St. Paul and I will wait upon you for your time which is always the best. Thank you for hearing my prayer and I believe that you will dwell in my home and bring back what I have lost in my family life. All Glory to you alone. In the name of the Lord Jesus Christ, I ask and pray. - Amen
