Really LONG STORY! I need advice PLEASE!!

So me and my partner moved in together Sept 2017 and found out we were pregnant January 2018. However, my partner left her job in March 2018 because she was finding it difficult with her pregnancy so all bills and everything has been on me. All she does in moan and complain and today I had enough we had this big argument and she left. She didn't understand what I was trying to say, I'm finding it extremely stressful that I have to do all of this by myself! And all she cared about was her feelings and she told me that she's never going to express her feelings to me again.

She said she felt she was existing and not actually living and I was explaining to her that only she can make that change. I've supported her through everything financially, emotionally etc and I don't know what more I can do. She's really down and depressed and I can't do much on my end. I just feel she's very ungrateful at times and I'm really tired of this whole relationship to be honest. What do I do???
