Break them up!! Kidding kidding! Don't really do that! What you need to do is if you really think or know that this guy likes you back then don't rush it! If he really does like you then he'll break up with his girlfriend and go after you! If he doesn't then he's just not worth it. Everyone needs someone who will do anything for them and if he won't then find someone else! Hope this helps! Good Luck!
Just tell him to break up with his girlfriend and you guys can get together
Tell him if he truly likes you he'll break up with her.
when she asks to go back to your place
Tell her to leave you alone; if you like her back, don't drag your girlfriend along.
I think you should make sure if he likes you and make sure he doesn't have a girlfriend. If he doesn't, ask him out or make it clear that you like him so he asks you out.
If a boy likes you and wants you to be his girlfriend you have to ask yourself if you like him back. If you don't you won't be able to spend time together. You both have to like each other.
MAYBE YOU SHOULD IGNORE..
If none of them like you I would suggest moving on and finding someone who likes you back and is not in a reationship.
I am currently in a situation with a male colleague. I like him, and I know he likes me. He has a girlfriend though. What should I do??
You need to choose one of them, and tell the other how you feeland be honest about it.
Just be good friends (Girlfriend-boyfrind if you want) It is that simple. if he/she likes you but he/she doesn't know you like him/her. Just tell him/her.
Well it souds like this guy has issues. I mean if he has a girlfriend then hoe do you know he likes another girl. And have you ever seen her. He could have a fake girlfriend to make other girls jealous. Guys have to feel superior.
