Heya and welcome to PC.

Personally thinking, does it matter if it was a mid-life crisis? I always think that's a funny label anyway - surely its natural to re-evaluate everything after some years?

I think what you do have is a fair complaint. If all your husband does is go out, or chill at home, its very hard not to feel fed up with the situation. Have you ever spoken up about this, and if so, did he try and see this and change his habits? I wonder if couples therapy may be a way to try and find out if you think your marriage is worth saving - if he can accept his faults and pitch in with the marriage.

But all said and done, if you felt sick at the thought of staying with him, and have felt happier since you moved out, then mid-life crisis or not, how can you ignore those signs? Only time will tell if you've done the right thing but I am guessing that you've thought for a long time over this issue, and its not a step you've taken lightly, so for now I guess this is the right thing for you at this time.

I would tho advise not to embark on a relationship with your old friend until you are ready. It would be the fairest for you, and him. I hope you'll be happy with whatever you do - its all we can do is to try and make ourselves happy.

Hugs.
