Are anda serious? That's wrong on so many levels. You're gonna just break up with your boyfriend just because somebody else asked anda out. That's messed up. anda figure out what anda need to do. I'm not helping anda with your soap opera shit.
Umm no! What kind of girlfriend are you?! To been consider breaking up with a man for his own friend! that is so shallow and rude. Not only will it wreck your relationship with guy one but did anda even consider what it'd do to their friendship. Gosh if I were him I'd end it with anda here and now!
Have anda ever thought about breaking up with Dom before this? Was it because of other boys? What kind of person is Tyran and would he make a good boyfriend? (I'm going to assume not. What kind of person asks out their best friend's girlfriend?) Are anda happy with Dom? If anda have to even ask this question, I doubt your relationship with Dom is very strong.
But only anda can answer this question. Think about how each boy means to you. Good luck.
Also, I would recomend asking for saran at link selanjutnya time. People at this spot tend to be a bit harsh. ;]
