Single mommy’s, how did you do it?

I just had my precious baby girl two months ago that I’m sooo in love with. Sadly though it isn’t picture perfect like i would have thought. Her father is just still so immature and comes from liars and cheater so he thinks that behavior is normal watching his mom cheat all the time... he’s cheated on me multiple times but swears up and down he’s done... idk if i believe that & at this point it doesn’t even matter. There’s NO trust. I have absolutely no trust in him & i hate feeling this way. I don’t want to live this way & i refuse to let my baby grow up thinking this toxic ass shit is normal. Only thing that’s keeping me from moving out is money.. 1.) im 21 & unfortunately i never finished high school, 2.) if i did get a job & work full time to support a home for my daughter & i shed pretty much be raised by someone else while i just work to keep a roof over our heads. 3.) I’m honestly scared.. I’m torn between sucking it up & trying to detach myself from this man while laying next to him or working a dead end job just to put a roof over our heads i need advice ladies I’m so stuck & just heart broken right now. More for my baby because she didn’t ask for this 🙁
