Stuck

I’ve been with my partner for about 7 months and I’m stuck about what to do.

After the third month we started getting into daily fights about if I truly love her or not and how I treat her. Everytime I mess up it is a cycle of the same things, whether I forget our daily meetup, go through a period of not complimenting her or failing to comfort her and understand her I always seem to mess up. I say I won’t do something any longer but then I end up doing it, usually unintentionally forgetful but then by that logic if I cared for her I wouldn’t forget.

This has gone on for so long and today my jealousy got the better of me and I feel really guilty. I’ve tried breaking up before and she always begs me back. She’s absolutely swamped with schoolwork and tells me that if I leave it will mess up her life. I think leaving is the right thing but I don’t know if I should given the current circumstances.

I don’t think I’ll be able to even be with somebody else as if I hurt one person this much I don’t think there’s hope to be with another.

If this seems really overdramatic we are both teenagers.

Any thoughts (doesn’t have to be advice) would be appreciated
