My boyfriend is on an overseas holiday, and it makes me so angry!
Oh, really? Why are you so mad about it?
I think he doesn't really love me because he went overseas with his former fling instead of me.
I can understand why you'd be mad. If she works works in the same company and it's a business trip, I could understand it. But if he went on vacation abroad with his ex-fling instead you, that really sucks.
I can't get over it because I know they're having sex. They're even posting on Instagram about it.
Yeah, you need to dump this guy. He clearly doesn't respect you, and dumping him will allow you to find someone who does.
