Sorry if this seems long but there is relevant background info and I don't want to drip feed!
Ex dp and I met at work and worked together throughout our 2 year relationship. We lived together too which ultimately led to the end of our relationship. I finished it just before Christmas as I didn't feel the same (and neither I think did he).
Shortly afterwards my parents leant me the rest of the money I needed to buy a house. Offer was accepted but the legal bit is proving to be very slow and there are a number of enquiries still outstanding.
In the meantime my ex has started to date a new girl at work. It is an open plan office and I have to sit watching them all day. I don't think there was any cheating but he definitely was flirting with her at the end (probably as I gave him no attention, we hadn't had sex for months as I didn't want to).
It's really difficult to watch them and be happy. I feel like the loser as I haven't got a new boyfriend yet (although I don't want to). I'm not sure if I can face seeing them in the future being loved up when I'm alone.
It's a small city that we live in and although jobs in my field do come up, I'm starting to think I'd have more luck in a larger city. I'm becoming more and more tempted to look for a work in my university town where I was really happy. But I haven't lived there for 4 years.
So really my dilemma is this, should I pull out of the house sale and cut my losses and move away? Or should I stay and hope I've moved on by the time their relationship gets serious?
