Ex gf is seemingly having sex with, and in love with a rebound a month and a half after our relationship ended?

[James]

The best way to eventually feel better is to ignore all of it. Learning about her love life will not make you feel any better. What will make you feel great is, when you realize that life has better things to attend to. That she's in the past and that her life is not of any concern to you. Living well is the best revenge after all (not that I am implying that you want revenge). The feeling is just similar.

However, if it makes you feel better, it's most likely a rebound. I take you as a guy with a decent head on his shoulders. Surely, you would have known if she's been seeing someone behind your back. Best keep the best memories, my friend, for the bad thoughts will only fester anger, resentment and hatred.

Like I said, she is of no concern of yours. Best move on to the next chapter.
