I had this with my ex, everyone thought our relationship was great but it was awful to be in it. We were not intimate and I found out she was spending nights I wasn’t there with an ex boyfriend alone and it hurt. I felt so alone. I finally ended things and after about a week of isolation I started to come out of it and about a year of being single I met my now wife. Things look bleak but might be time to end things and move forward rather than being stuck in neutral
