26M, my wife is leaving, I’ve been feeling extremely self-conscious and ugly. Hoping I can get some insights.

Wife said she hasn’t been attracted to me for most of our relationship and realized it was a problem when she started to ‘get to know’ her handsome coworker (claims it wasn’t anything to do with her paramour but just doesn’t love me anymore and isn’t as happy at home as she is at work.. there’s more to it but this isn’t the place for that) Now she’s gone. Already got rid of my glasses because she criticized those too. Been trying to exercise to build some muscle. I’m very fair skinned and freckle/burn easily which I feel certain is a contributor to my lackluster appeal :/

Any tips on where I can improve?
