Do you live in the same town as her? I moved here to be with her so once I am further away, I am expecting to heal much faster.
Funny you should say that. I moved 600 miles to be with her. Naturally, her social group became mine, she isolated me sucessfully from any potential new friends that she considered a threat and in the end I wanted to hang out with her and her alone.
I feel as though, after 2 years of living here that I've suddenly landed in an alien environment even though I work here, have my own place etc. She works around the corner from where I live and have had to find new routes to avoid seeing her car and possibly her.
The places we used to go out are now off limits. She has an incredibly low tolerence for boredom and I now seem to view most people in the same way. It's ultimately shallow and needs to be got over but it is a kind of drug.
