Does your husband trust that Jesus Christ is Lord and Saviour? Because if he does, he needs to be shown how evil and bad adultery is. And that you can justify divorce based on what he is doing, although restoration is definitely better! And if he does not believe in Jesus, we all need to pray for his salvation.
Do you trust Jesus Christ as your Lord and Saviour? I am hearing a lot about churches and masses, but I believe the Bible is clear that we are only saved by the grace of God - not through a church or mediator.
My thought, besides the marriage counselling, is for you to read the New Testament, to start. Get a Bible you can understand, and start in John. Then read Matthew, Mark and Luke. Read John again, then go to Acts and the epistles. You can read Revelation, just be aware there are a lot of weird symbols and it can be hard to understand, or worse, some people badly interpret it.
Then put Jesus on speed dial. Not the rosary, but Jesus! Nor Mary, but Jesus! Ask him to help you, to guide you and lead you. Ask him to comfort you and to change your husband.
"Heavenly Father, I just pray for Lozzlana, that you will become very real in her life. That she will realize that you are the way, the truth and the life - and that no one comes to the Father but by Jesus Christ. Hold her hand, help her through this trying time in her life. Bring solid Christians into her life, especially women who can pray with her, and lead her without judgment. I pray for a restoration for her marriage, meaning that her husband will repent, and figure out why he is cheating and why he has been putting his gratification first, instead of their marriage. In Jesus name, I pray, Amen!"
