This is a long one, I need advice.
Background story, been with my partner 4 years and we have a 5 1/2 week old baby. He has a history of speaking to other women, I caught him up to no good when I had been home from hospital after our baby was in NICU for a week and only 9 days old. He insists he didn't message the person but I know he did deep down. My own stupid fault for trusting he could change, I know.
I also found out whilst pregnant that he didn't want to be tied down to me and wasn't sure if he actually wanted to be with me. And I have since found out he's also cheated during our 4 years, this is a new discovery and I haven't spoken to him about it because I'm not sure how and I don't want to argue in front of our baby, he is a very defensive person and will refuse this has happened.
I quite frankly don't like him anymore, he is hard to live with, childish, doesn't do fuck all around the house or to help with our baby. Spends his time on his Xbox or planning things with his friends, we have done nothing as a family yet! I am completely and utterly done with him.
I don't want to teach our daughter to accept these behaviours by staying with him for her sake. I want her to always know her worth.
My problem is, we currently rent and he's the breadwinner, I don't possibly see a way for me to leave as I have no where to go and I can't afford staying on maternity pay. I have family but their homes are full. I am also in debt on my credit card due to him and I'm worried of being left with these financial problems if I walk out. I have put up with his behaviour for so long that I can carry on doing so to plan my way out of this relationship and not make a complete mess of mine and my daughters life.
How do I do this? How do I get out? I don't know where to start, I see no way out and completely trapped.
