I'm not in the same sitch, but wanted to tell you that separation has been the best thing for me. I am so much happier now. I have had anxiety-free time to reflect on our R and realized how much better I deserve.
xBF said he wasn't miserable, just thought he wasn't as happy as he could be. But he wasn't willing to put any effort into improving our R, he thought the best way was to just walk away and start over fresh.
So I gave him what he wanted. He wanted to hang around for an indefinite period of time and eventually leave on his own terms, but that was not going to work for me. And ultimately he got his freedom which is what he said he wanted. Now he's having second thoughts. Apparently the separation has shown him that there were good things about us. Funny thing though, it's shown me that those good things aren't enough for me anymore.
I think you should consider a real physical separation. It will give you time and space to figure out what you want for your life moving forward.
If you love somebody, set them free. http://tinyurl.com/2empx2g
