Need help

I’m in high school (17) and just broke up with my girlfriend of a year. I still love her very much but I broke up with her because she would always go out and hangout with one or two of her friends (who were girls) and they would hang with one or two different guys, and I was never invited by her to tag along. I even asked a while ago why she never invited me and I would tell her how it bothers me that she hangs out with guys like that when I wasn’t doing it with other girls. Everytime I would bring it up she would tell me they are just friends and say that would never change. I eventually got tired of it especially when she would hangout with her friends and they would go to this guys house who doesn’t like me and she knew that. So I told her I wanted to breakup and then hours later she told me she thought about everything and said that she won’t go out and do those things anymore. Now I’m confused because I still love her and want to be with her but I felt different because it felt like she didn’t respect my feelings until she finally realized that I would break up with her over it. Any advice would help thanks.
