We are 3 years into relationship, neither of us cheats,
the problem is now that on the first week of relationship, the guy still in contact with her ex because he wants to help her on her university, he made a promise on her ex to help her on the university application, but the F22 confronts him about this and thus he does not help his ex with the university, fast forward 3 years into the relationship, the F22 would bring this matter back and tell her unsatisfactoriness about this and cant move on, during the period of 3 years neither the M22 and F22 cheats nor having any friend opposite of gender, the F22 really thinks that she cant move on with the first week issue, whatever the guy do, she will always remember the first week regardless.
What should the M22/F22 do?
TLDR, guy keep mutuals on instagram with his ex on first week of relationship, woman (not ex)unsatisfied after 3 years into relationship even tho the guy cut any kind of relation with the ex
