I want to help you through this. I can't say that I know how you feel that I am right there with you , but I can tell you what helps me through my hurt and storms and I believe will also help you first of all we need to realize that God didn't do this to you, man did . second God would and even asks in His word that we forgive people who sin against us Mt 6:14For if ye forgive men their trespasses, your heavenly Father will also forgive you:Mt 6:15But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.
Now I know this may be the last thing you can do, but keep the thought that you will have to forgive This man at some point in order not to hinder your walk with God. your kids are watching you and you can teach them a very important lesson in forgiveness as well in Love or in hatred and in vengeance. Keep in mind that He is also their Father what you say around them about him could drive them away from you.
Now God understands if we, in our storms, ask why God, although you may not get an answer right away. But I have learned over the storms in my life, that to ask Him where He is at, is a lack of faith. Because He has already promised you that He would never leave you nor forsake you, so no matter how dark the storm we need to look for the Light for He is with you. stay focused on the Light. here is what we need to pray Help me Lord. don't let this storm destory me. help me stay focused on you, to walk in the Spirit and not the flesh, help me to stay true to you, help me be the light to my kids that they and others may see your Light through me. help me endure this storm, help me with the love and forgiveness that You would have me pour out on those who have hurt me (not only your husband but also the other person involved) Lord as you have promised from your Word please be my strength in these times of my trouble.
there is a lady at our Church just went through the same thing except the father-in-law part , she made a prayer request right after she found out , that she knew the lady personally and that she knew that she wasn't saved and her prayer request was for the other lady's salvation, only to have the other lady to find out that she had been praying for her, she laughed at her for praying for her. but currently The lady from our Church and her husband are trying to patch things up and get back together. then as the first response to this thread said remember
Ro 8:28And we know that all things work together for good to them that love God, to them who are the called according to his purpose.
the last hurt from a loved one that I went through God said that the one that comes out of the storm with love on their hearts come out on His side. unconditional loves is what He pours out on us and unconditional love is what He expects to be poured out from us to others
