So me and this guy have so much chemistry we flirt a lot and I really like him and I think the feelings mutual we went through that whole do you like me stage like all semester and it's almost over once I was flirting with this other guy and he showed me a pic of him and his girlfriend! Yeah he has a girlfriend :( but I'm pretty sure they've been going out for less then a month I know it's wrong but I tried to get over him and ignore him but he just has a way of reeling me back in he's just the type of guy that you just have to love he's such a sweetheart and a great guy I don't know what I should do I wanna fight for him but how?
If you want to fight for him. You have to be careful not to over step your boundaries. Be yourself and light flirting goes a long way. Make him see what he is missing but not in a "slutty" way. I would also look around for other guys and don't limit yourself to a guy who is taken. Maybe you'll find someone or at least you may make him a little jealous. Good luck.
The only warning sign I want to send to you is think if you do get together what if he does to you what he did to his girlfriend? He did it once, so he could again. Good luck girl, guys are difficult!
