I need some encouragement...please

I’m going through a lot right now. I just found out that I’m pregnant with baby #2. I was so excited at first but my partner quickly dimmed that. He is telling me I need to get an abortion. He is right I should abort this baby because I have no help. He doesn’t help with the first. He works 16 hrs a week and plays video games all day. While I take care of our baby girl, work 50+ hrs a week and going to nursing school on top of that. I am so hurt by all of this last night while we were talking about abortion he started laughing out of nowhere because “it is funny”. I am crushed he takes this all so lightly. The only time we ever spend time together is at night when he wants sex. I know I need to break up with him but i’m just stuck thinking about breaking up our “Family” or thinking about him with someone else hurts. He is constantly putting me down and calling me a bad mom bc I get frustrated when he won’t help. He even told me I should’ve never had my daughter. I know it sounds so simple like bitch fucking leave him but it’s really not. Any advice or words of encouragement would be greatly appreciated.
