Hi Charlotte, welcome. Your story is similar to mine, for a while i too tried to supress feelings with alcohol - and we are almost of the same age - i'm some years older, but, please don't tell this anyone
My ex-wife didn't accept my coming out attempts, and now i'm divorced now. I've been victim of a sort of "stalking" - my ex persecuted me for a while... but this happened many years ago, i get over that - past is passed out.
She was just invidious for I looked as a much more beautiful girl than her

Now i'm in a new relation with a more open minded girl.
It's really great that your fiancée is supporting you.

All the best Charlotte, I'm very happy for you.
Hugs,
Aly
