No infidelity involved, but my partner of 2 years initiated a breakup out of the blue in the middle of a mental health crisis he was having. He’s safe now, we’re both in individual therapy, and have both decided to stay together to work on our relationship and ourselves. Although we’re better now and slowly rebuilding our relationship, my anxiety is at an all-time high and I honestly feel like I’m going insane with my overthinking. I have severe trust and abandonment issues stemming from past relationships and my estranged relationship with my dad, so for someone I consider my best friend and my person to do this has just shaken me to my core.
There were no signs or clues that a breakup was about to happen. I’ve wracked my brain since then to try and remember if there was anything I could’ve missed, but I was entirely blindsided; it feels like a rug was pulled out from under me. We’ve been communicating a lot more openly and honestly which has been great, but I can’t help feeling like the relationship I used to know and feel safe in is completely gone. I feel like I’m grieving. We’re both committed to working on our relationship together, but how do I learn to trust again?
TL;DR: partner initiated a breakup completely out of the blue, but we’ve decided to stay together. How to learn how to trust him again after feeling betrayed?
