it's either you confront him or brake the so-called "friendship" between the two of you. The reason to this is that you can never call someone who betray you- a friend. If you do, you are lying to yourself or you are confussed!
Do some research, find out if he has a girlfriend.
It really matters how severe the flirting is. If she flirts minorly with a lot of people, it may be because sh just naturally flirts with people. she flirts with everybody. kinda like me. if she concentrates on one person and flirts heavily with that one guy, then you may have a problem. dont break up with her, though. talk with her first, and ask if she has feelings for this person. talk it through and see what happens. good luck!
Even though it feels like you should, dont bother, its pointless and causes embarassment when your older, but if you must there's not really any way to get a girlfriend, It'll just happen.
In my opinion you should just keep dating her and if this ends you should break up with her so that there isn't a reason for her to break up with u so u don't look bad and ignore or don't bother her friend.
I am not saying this is the truth, but either his girlfriend was not nice, or he just wanted someone to mess around with.
It means 1.He going to break up with his girlfriend.2.He is a cheater.2.He just wants to get to kno u better so if it doesn't work out with his current girlfriend.
I would reject that two-timing scum hard and ask his girlfriend why she hates you when its her boyfriend who is trying to cheat.Were you and the guys girlfriend friends though.if not,just stay away from these people.good luck!
You don't do anything. If it is his ex and she contacts him then he is going to have to explain to her that he has a girlfriend (assuming your together) and he has moved on and so should she. If the ex is just around and not bothering you then don't let it bother you.
Flirt back and make him want you.
no that's just discusting
He is probably just a flirt than... sorry :(
Just because he speaks to you doesn't mean he's flirting with you, although if he is, he may just not think that flirting isn't allowed just because of a relationship. Don't get your hopes up.
