You and her are both involved in a love triangle. Tell her to make up her mind on either to pick you as the one for her or the other guy for her.
Well if he broke up with her, she might still have feeling for him so just ask her that your feeling like she might be showing emotions for him and ask if it's true or not. And if you two are in a committed relationship, she should tell you the truth.
If you are in a relationship, then you disregard the other person who likes you. Loyalty is always better in the long run. Also, you should realize that the grass is not always greener on the other side. If you are available later, then perhaps you return the "like."
Answer You should be able to tell by how the person responds to you. If you already know that the person likes you, that should make it a lot easier. If you are not sure, you should probably move slowly towards a relationship and if that person keeps responding to you in a positive way you will know when the time is right.
A lover.. :) Or, they can be needy?
He's not a good person if he likes you and has a girlfriend. He should either be completely committed to this girl or should dump her if he is not into her anymore. He should finish his relationship off with this girl before he goes liking or looking for another girl.
umm ask the person...be honest, its the first step to a healthy relationship
Several things can happen if a gay person likes you. You can allow the relationship to go on if you feel the same. However, if you feel different, you should make it known in clear terms that you are not up for such type of a relationship.
Wait for him.
Well, first off it depends on how much you like the person your in the relationship with... If you think about it and don't have that much feelings for him then you probably should end that relationship, it's not good to keep leading the person on if the feelings aren't the same. As for the other person you like you should find out if he likes you and what you like about him, however don't try to rush into another relationship right away...
I think you should depend it on how your relationship is in the friend zone with them. Which is nicer for example...
because it makes people feel happy and not lonley, its a nice feeling to know that some one out there really likes you
Curb your appetite and secretly hope that their relationship does not work out.
