I was thinking something like joking around:
"So what? I have a boyfriend too! We should meet up the four of us so they can become best friends."
Something that DHVs or Teases them would be better I guess.
Just a moral note: Even if they really DO have a boyfriend, and you use your PUA skills to get the girl, the boyfriend is obviously not doing something right. Its his fault that his woman is out there seeking other men.
Anyways' any suggestions?
I'm pretty sure I read a thread like this before, but I just forgot what it was called and I cant find it.
