After breaking up with my ex-girlfriend of nearly 4 years, she got a boyfriend 4 weeks later. They worked together and, based on her posts, he was in love with her before and she loved him back after a few weeks of dating. Now it’s 10 months after the breakup and she says they’re moving in together and planning engagement.
I’m having a very hard time getting over how fast she moved on. At first I thought it was a rebound, but I’m increasingly believing it’s the real deal. I know she loved me very strongly and that I was her first love, but I feel so easily replaced. I want her to be happy, but thinking about her makes me miserable now. I obviously try my best not to think about it, but it’s difficult sometimes. Any thoughts on the situation or insight to help me through this?
