Hey loves! I need help

Hey loves, so I’m going to make this as short as possible but I could really use any kind advice. Please nothing rude.

Im exhausted of trying, been with my husband for two years now, we have been through a million ups and downs. As far as a week ago things were amazing between us, suddenly one night he decided to start being a real douche bag and suddenly a few days later ended our marriage.. no remorse no emotions to show.. just said he has to work on himself… I have been sick to my stomach but trying to avoid that this happened. The other night I broke down crying asking him why are we still living together and why he can not give me a real reason for why he ended things.. he began to record me when I started to cry more, I got upset and went to go next to the nightstand that was right by him to grab my phone charger and he up and swung on me, bruised my jaw, but then right after that he punched me in the stomach… we have been trying for a baby so when he did that I was shocked and beyond hurt.. fast forward he has been so rude, and disrespectful. Told me that were still friends and that maybe one day we will be together again, and when I try to tell him how much this is killing me to feel like he is just stringing me around he blocks my number and ignores me… last night I made his favorite and not once did he say he appreciated it… today same thing I made a wonderful dinner and he can’t seem to be bothered.. at this point I don’t know why I’m still holding on, or why I haven’t just packed my stuff up and moved to my mothers house so I can start over.. but I’m mentally and emotionally exhausted.. I just don’t know why I have not left yet and I feel so lost.. im only 22 so I know I should be happy and feel free but I don’t…

Any advice or even your own similar stories please feel free to share with me.
