explain her the situation frst and assure her that you love her and only her...the posessiveness obsession and jealousy are because you dont want to lose her..talk to her and make it work
Tell her how you feel and fear of losing her is making you worried.
Give space and trusting your partner is a very important part of any relationship. Try to do it.
Talk to her discuss things that bothers you or discuss your expectation, ask her expectations and tell her that it’s something you value so much and just because of this reason you don’t want to lose this thing.
All the best.
I hope she will understand.
try to heal yourself first and then go back to her. heartbreaks can be terrible
I hear you. I think that you should talk to her and explain to her that you really do love her and that is why these things come out.If she decides to give you another chance make sure to work on those trades.You can even ask her to help you and what you can do to chance those things that she doesn't like.But also remember don't push yourself to a point where you end up feeling worse.
all of the best.
