I know you guys are right and that i need to dump my boyfriend but i also don't want to end up old and alone either.

It seems like you're all over the place on this and tbh, it seems very one-sided to you. If you're unhappy in your relationship, then sticking around just so you don't wind up alone isn't going to be of much practical use. On the other hand, if you think you can work things out, then you should be doing that instead of pining away here.

There's a choice that has to be made. It's one way or the other. Which way do YOU want to go?
