I'm (18F) Scared to Leave My Boyfriend (19M)

I have been dating my boyfriend for 2 years. I always felt like he was the one for me, I have loved him with everything. We've had quite a few problems, however.

At the beginning of our relationship, he still seemed to be attached to his ex-girlfriend. To this day, he still claims that he didn't have feelings for her, but I truly think he did.

Another issue I've had with him is his mother. She treats both my boyfriend and her two other sons (who are both in their teens) as toddlers. My boyfriend doesn't do his laundry, knows how to cook, or cleans his room. She's also very overprotective and has a tracker on his phone.

Furthermore, he has a lot of issues with procrastination. He's supposed to be starting college this year, but he only filled out his FAFSA a couple of weeks ago, and it took him another week to actually apply. Classes start in under two weeIks, so he might not be starting at all this semester because his transcript from high school hasn't been sent over yet.

He also has an issue with a male friend I have, who's my only friend. He has repeatedly tried to tell me to stop being friends with him, but I've refused. My friend and I aren't that close, and all we have been doing is working on making a game together. I've expressed to my boyfriend that i only see him as a friend. I don't want to be more alone than I already am.

Finally, he seems to have no ambition. He claims to have a goal in life (insert blue collar job here), but he never practices it outside of school, and he doesn't seem that interested. His family is also pretty well off, and they're always going on vacations almost every month. If he's going to continue with that trend (which I think he will), I don't know how he's going to hold any sort of job.

I'm scared to leave because I love him so much, I've only had one other boyfriend who was awful to me. My current boyfriend seems to love and care for me a lot. I don't think I'm going to find anyone else, and I really don't wanna be alone. What would you do in this situation?

TD;DR: I've had multiple problems with my boyfriend that make me think he's not the one for me, but I'm too scared to leave him because I'll be alone.
