prayers please

i am 9 months pregnant with 2 kids. married for 15 years the last 10 have been bad. husband is a functioning addict . today found a fake facebook account he had and had been looking up girls on. it was from a few months back but still I was lied to about it and it is wrong to have a fake account. I have been praying for him to change but now I just find myself praying that I can get away from him and be able to take care of my kids on my own. I give up that je will ever change he is a big time liar. I do not trust a thing he says. I am so unhappy and feel so low about myself. he has all the money. I am a stay at home mom. I just hope and pray that I find the answer. I am feeling so lost, lonely and like its hopeless.
