so after a long relationship with my gf she broke up with me and after few days she started dating someone that had the things that she missed in me like being so jealous and having a good relation with her family but after 3 months they broke up and i didn't know about all that then I started talking to her not knowing that she had another relationship and she swaped me . after 3 weeks of talking and getting together she told me about it and know I really don't want to loose her but ther is that feeling of lost trust and being swaped and replaced that made me want to leave her but I can't coz she really regrets that and she knew that i couldn't be replaced by anyone and i don't know how to get rid of that bad feeling and if it will go by time or not
