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

I've been dating my girlfriend for almost year, things are great when we are together, we have fun, we get along, we enjoy travelling together, staying at home together, hanging out with family, generally things are good. My issue is that she is friends with a group of people that I was formerly friends with, but with whom I've had a significant falling out. Essentially, we had the same group of mutual friends before we dated, when my previous relationship ended, so did some of those friendships. She still hangs out with them on a regular basis and really does enjoy their company and they are good friends for her. I've tried multiple times to reconcile and make things better and hang out as a group, but honestly I don't think it's in the cards. It's painful to hang out with that group, and honestly it's even hurtful when she hangs out with them, mostly because they are doing the exact same activities that I used to be included in and frankly that I started up (sports teams, trips, etc). She knows it impacts me at a high level, but I am not at all trying to control her, so I don't always let her know that each time she goes and spends the day with my former friends, that it hurts. I think my hurt is mostly coming from resentment for those people and what's happened between us, possibly some jealously as well. I really do want her to be able to keep those friends and I really do want to keep this relationship. But when she's out doing the things that I used to do with that same group of people, I feel resentment. 

Looking for advice on how to "make this work" for me and for her. We've talked about it many times in the past and she acknowledges that it impacts me, but it remains an ongoing issue.

Any thoughts/suggestions/slaps-in-the-face are welcome.
