Is it normal to regret or second guess such a big decision? 

I left my husband of 4 years earlier this year, after a years separation and a few counseling sessions. We had been fairly unhappy since our first year of marriage, but had been together since we were 18, so we figured we would work things out eventually. I left because I always felt like we were on two different pages, mentally and emotionally, and I couldn't handle it. We just never were in synch. It took me more than a year, and some couples counseling to decide that divorce was the right thing for us both.

I also thought I had feelings for a female friend of mine - and assumed that was a major reason why we weren't very compatible sexually. However, after I'd left, I no longer felt the same attraction for her. I don't understand what was going on there at all... 

I've dated a few men, and I've met someone I like, to a degree. He's a nice distraction, but I really, really miss my husband. We've had minimal communication since July, and are proceeding with a very civil divorce, but I'm wondering if I've made a mistake. 

Or maybe this is just part of the process of grieving the loss of a very significant relationship? I want to bring it up to him and see how he feels about it, but being that he was so very hurt when I left, I think it would be selfish of me to involve him at this point. I don't want to leave him twice. 

Anyone been through this?
