What to do?

Not sure what I'm asking here maybe just need advice...
I'm currently single and 7 and a half months pregnant. Long story short was married had 3 kids finally had the courage to leave him. It was a domestic violence relationship. Ended up with a 2 year avo in place.
Skip forward met a guy fell in love!!! We got engaged than he cheated. He never slept with her but got a new phone went on dating sites met up with her and kissed her. The only reason I found out was because she found me on Facebook. I wanted to move forward but not forgive or forget what he had done. We were trying for a baby even went to a fertility specialist. Finally fell pregnant had some issues with the pregnancy and baby early on so I was very Moody and scared but baby is fine now. One weekend things didn't feel right I asked to see his phone as it's always hidden And on silent. So he told me it was in the garage as I want to look for it he packed up and left me.
It's been 3 months now.... He wants to move back home but I won't allow it until we seek help as in a relationship councillor. Anything he doesn't like that I send in a message about us or asking why he hid his phone he just ignores me. I'm so angry and hurt thought I was his forever when he asked me to marry him.

I'm so lost due to my hormones right now.... one minute I want him the next I know i deserve better
