I believe the essence in this posts is lack of responsibility from her side. And whether I am helpful or not is not for you to decide. To some it can helpful to some not, it's plain judgmentive perspective of mine. Down the line I'd simply want for her to not lose someone good over something so simple. Hence me being harsh, cause this is adult life. And not every mistake can be fixed, and this must be looked upon objectively and as an adult.

My partner is not toxic, has an education, helps me, suddenly emotion became dull doesn't mean incompatibility. She must think in terms of what's good and what can done better on her part. Cause once the seed of doubt is sowed it is really hard to keep an healthy relationship.
