<human>: Can you succinctly summarize the text in 1-3 sentences?

Been together for nearly 6 months now and I love her (at least I think I do?) but I've never really been the relationship type. It was either I committed or she left me and I didn't want to originally and she flipped out, crying and such. I felt bad and committed to her and we've been together for almost 6 months. I really care about her but I miss the single life. Every time I see an attractive female when I'm out I can't help but look. I just don't think I'm satisfied with my gf if I'm doing that. What should I do?
<bot>: miss being single but love gf. I feel like I'd be a bad person to break up with her. Not sure what to do.
