Need Advice Please, unmarried with two babies Options

[DestinylovesJesu...]

Hello everyone,
I would really appreciate some advice on how to handle my situation. I am in a relationship with a man and we have two children together, ages 11 months and 25 months. Their father and I are not married. We are both have accepted Jesus Christ as our Lord and Savior. However we are at different places in our walk. I want to grow as a christian and be a good example to my children.I am heavily convicted that we are not married and are living together. I have told my children's father many times how I feel, that I would like for us to get married. He always gets annoyed when I approach him about it. I come from a past of drug addiction and abusive relationships, etc. God rescued me from it all and I am so grateful for His grace, love, and mercy. My children's father has said more than once that basically I should just be happy the way we are, considering where I have been before I met him. Recently he has told me that "we don't even get along, why would we get married?". This has hurt me deeply and caused me to wonder if he ever plans on marrying me. I feel we are just "playing house" and he has no intentions of committing to me. We have only known each other for three years and have had two children in that short period of time. He is a good dad and good man for the most part. We have had some serious struggles. For example he recently admitted he was addicted to pornography (which I have known for awhile) and I discovered he was going to an all nude strip bar with his 20 yr. old cousin. I forgave him because he admitted he needed help for this problem and agreed to see a counselor. We went to a christian counselor 3 times and my children's father decided he did not want to go anymore and we could not afford it. I am not trying to judge him but the choices he is making have brought spiritual struggles into our home. I am a stay at home mom and have no income, alot of debt, warrants for my arrest from unpaid tickets from my past. I thank God he has given me a new life. Considering the path of destruction I was once on- It is a miracle that I am still alive and now have two beautiful,healthy babies. I am thankful to my children's father for being a good provider. However, he has told me on many occasions that everything we have is his and not ours. If I left him I would have nothing- no car, no money, no place to live. He also said he would not give any child support if I left and in fact he would fight to have the babies. Please,I desperately need some Godly wisdom and advice for my situation. I don't know what to do
