I mean if I've invested 3 years of my life in this woman, then yes I'd want to know.
The OP is leaving out a lot of details, but there could be any number of factors at play that could be fueling her feelings. If I love this woman, I'm putting in the effort to identify and address the issues (outside of infidelity) instead of just letting her walk![]()
Thats how you end up getting gaslite and manipulated, the cycle of trying to repair an unrepairable issue

Facts.
she moved cross country for OP, to his place/his domicile...Whats for her to be confused about?
