<human>: Can you summarize the given text in a few sentences?

First post here, so be gentle with me. I started hanging out with my current girlfriend in the end of spring and developed a FWB relationship over the summer. We've been officially together now for a month but we could might as well call it 4 months because we were monogamous even during the FWB period.

I really like spending time with her, we have similar sense of humor and at the moment I think she's as close to a female version of myself that I can think of. Which is awesome. And on top of that she's gorgeous.

The problem is, though, that I'm really into self improvement and I see myself as a completely different man 10-15 years from now. And that future version of myself isn't compatible with her anymore. So I'm pretty sure this relationship is doomed to fail at some point. What I'm asking is do you think it's a bad idea to commit time and energy on a relationship you know will end at some point? We have an honest relationship so I've actually talked with her about this and she thinks I'm overthinking and should just focus on the here and now instead of thinking so much ahead. I know she's kind of right, but there's just this nagging voice in my head that tries to sabotage the time I spend with her because in the back of my mind I know things are eventually going to fail.

Do you think we should just keep on having fun together, should I try to get rid of the fear of failure and think about the future when it's actually time for that? Or should we break up before we get too attached to one another?
<bot>: I like my girlfriend at the moment but she's not wife material. Should I still try to focus on the relationship or break up with her?
