What do you mean by if this relationship salvageable? She ended it so there’s no relationship. Nothing to salvage. At this point I’d move on.

I recommend that you stop showing up at her school. She stated she’s uncomfortable so respect her wishes.

As about what went on in a relationship, sounds like too much drama. And I’d not date anyone who doesn’t introduce me to their friends for over a year. Sounds like there’s major lack of commitment and she got tired of it.

Also you both lacked trust in each other. What’s up these spyings and stalking and checking up on each other phones. Both of you. Unhealthy.
