Jag, like you I met a good man that was "exposed"
I too had a very long term relationship that failed as did my ex and we wanted this to me our last ride and be together.
I'm 44, and though I am hit on a lot, I am not interested in other men. I don't every worry I'll end up alone because I am a relationship person, but I need to take my alone/single time to look out for me now
To get healthy so I can meet a healthy man.
It's all based on fear. If I could make my ex's addictions and abuse just disappear, I would, but I'll settle for self love, self respect and sanity right now.
I know how you feel though
