I’m such a mess. I need help guys

I just got a faint line on a pregnancy test. I’m 18 years old. Me and my boyfriend broke up over a month ago and I started sleeping with my ex two weeks ago (me and my other ex bf didn’t sleep together for like a month prior to breaking up) and I’m so confused and scared. When i saw it I was kind of happy? And now I’m crying and scared. My ex boyfriend the father wants me to have it and is happy, but me and him broke up to him cheating on me and although I still love him I just don’t want to be a single mom at 19 im a waitress I make okay money but I can’t work forever and he doesn’t even have a job currently or a car and I’m so fucking scared and my whole family is going to be so disappointed in me. If I have an abortion I kno I will feel so guilty and sad. But if I have it I know my life will be hard. I just wish someone could choose for me. I can’t do this on my own. Either way I feel like I’m making the wrong decision 😣
