I want to be able to go out with this girl. Anybody have any advice for me to start talking to her again and make her want me over her boyfriend?How to get a girl with a boyfriend?
ok bud. well first i suggest you try to find out why you guys stopped talking. ask her friends maybe? this way, you can prevent it from happening again. also, don't be a stalker, but try to see how her current boyfriend treats her. if she really likes this guy, try treating her the same way. or even better! if you can't get close enough to her to do that because of her boyfriend, maybe start talking to another girl. if the girl you like sees how nicely you treat this other girl, she might start to get interested. THEN you start talking to this girl again. but dont get beat up in the process! its never a safe or smart idea to mess with another guys girl. so talk to her, be sweet, and when they break up, she'll already have an interest it you!How to get a girl with a boyfriend?
Just start talking to her or txt or facebook or something and tell her that we haven't talked in a long time and we should hang out sometime. maybe she misses you too and likes you and you dont even know about it
ok the guy who had the extremely long paragraph is WRONG! I'm sorry but you cant use another girl to get what you want. The other parts though were helpful like trying to treat her better than she does but if she really likes the guy i think u should just wait until they break up
don't ruin someone else's relationship!!! find someone else!!!
be her friend and then move in for the kill
