Left my abusive husband

I finally had the guts to leave my abusive husband 2 weeks ago with my 17 month old son. I recently went back to work and I was very nervous about leaving my son with him because I have done EVERYTHING for him up until this point. All he does is play video games and drink beer. 2 weeks ago was my final straw, I was getting ready for work and he was sitting playing videos games while my son was off on his own. I got so upset, I told him I was taking our son to my parents while I go to work because he clearly can’t handle it. I packed an over night bag as I work till 11pm and I was going to stay the night at my parents as well in case my son woke up, they wouldn’t have to get up with him. He got so mad, he rented a uhaul and packed up all his stuff and left, told me he would be back the next day for the rest of his stuff. He came back the next day and hasn’t left since. I’ve been staying at my parents this whole time, he left me and my son with 400$, my old broken car and shut my phone off. I have an appointment with a lawyer next week. I just found out yesterday that I’m pregnant 😭 I’m full of emotions. Scared, angry, nervous, excited because I’ve always wanted 2 kids. I had a miscarriage in October and I’m so nervous for that to happen again but at the same time feel so horrible that I’m having another baby with this loser. I would love to hear some encouraging words.
