Do I get an abortion?

I’m currently struggling with my decision. For reference, I am 24 years old with a 4 year old. I am 11 weeks pregnant, I was very excited at first. My kids dad has not been great and honestly for the past almost 5 years it just been off and on. We currently live together and the emotional abuse is just unbearable. As much as I want to be a mom of 2, I just feel like it’s not feasible given my circumstances and mental health. He’s a great dad, just not a good partner. I really do not see a future with him. I feel so stupid for letting him get me pregnant again. He’s constantly telling me when he gets the tax money he’s leaving (which mind you he’s the main source of income). I’m being pulled back and forth if I want to go through with my decision. I have support from my mom and my friends. My mom is even willing to cover the cost for the abortion. I just don’t know what to do and I’m really at a loss but I need to make a decision quick as my pregnancy is only advancing :(
