<human>: Can you give me the gist of the text in a nutshell?

I have to be honest, I'm not entirely sure I want to break up with my boyfriend. I'm in love with him, but I know we want different things from life. We started dating when I was pretty young, and this is the first real relationship I've had. When I went to university two years ago, we got a place together. He loves me very much, and I guess I feel comfortable, but this isn't how I imagined things.

All our friends, are really his friends who he has known for many years, and they are all starting families. My boyfriend wants to get married and have kids. I want to finish college, advance my career, and travel; none of these things does he really "support." Of course, he has other flaws too; he is extremely vindictive and possessive. He has told me in the past that if I broke up with him, none of our friends would talk to me, and I would never get to see our cats (who I love very much). 

I know I can't count on friends, and I'm essentially disowned from my family. Many of the things in the apartment I have paid for (bed, couch, tv, etc) but I don't have a car and no way to move them. Worse of all, after paying bills every month I don't have anything left to save to get my own place. Basically, I think it would be easier to stay than leave. 

I would love to hear from anyone who has done through this before.
<bot>: Should I break up with my long-term boyfriend just because I want something else from life, and if so, how?
