Hey so me and my gf were together for a year now.. But in the last 3 weeks i was rly kind asshole, was really demotivated, felt bad and didnt treated her as good as before and on this weekend we werw out with her friends and on some time i just left the group without saying anything... Well that broke it, yesterday we talked about and she told me she cant take it anymlre.. We kinda agreed to give us a pause until next week.. Im rly scared to lose, its not my first relationsship but for this one i just dont want to lose it

Any Advice how to get her back?
