Boyfriends ex gf of 3 years is coming home the weekend of her birthday at the end of the month..which is oddly enough the same as mine.

She has a new boyfriend whom MIGHT be coming back here with her, not sure...and theyve been dating pretty much since she broke up with him(him being my dude), and shes seen my dude a couple times right after they broke up before I even knew him...but they never got back together.

Should I be as worried as I am? Im anxious and nervous about it all.
