It depends. If you want to be in a realtionship with the girl you need to talk to her and see what her feelings are on the situation. If she says she just wants to keep it a secret and that she doesn't like you in that way , that means you proabley don't want her as a girlfriend anyway. Would you really want to date a lying cheater? If she wants to break up with him then yeah , game on!
Ask your boyfriend. If you don't trust his answer he shouldn't be your boyfriend.
It means she is about to dump her boyfriend and pursue you.
yes
No, the girl is cheating. You´re just an a s s h o l e.
You should tell the other girl and both break up with your boyfriend.
If he is her boyfriend, hopefully, she would like him.
At this time there is not much you can do as she has a boyfriend. It is best to focus your interest in another direction and move on.
Hit puberty?
People can fall in and out of love, but, both of you were wrong in what you did. Sex alone doesn't make you fall in love so if you're betting a one night stand of sex is love forget it! If you loved each other and knew it then she should have broken it off with her boyfriend. When in doubt, both of you should put yourselves in her boyfriend's shoes. Not a nice feeling is it! Since you think you are in love then she is going to have to break-off with her boyfriend, but it would be wise not to hurt him further by telling him she has slept with you. If she isn't willing to do this then she doesn't love you enough.
no
If a girl has dumped her boyfriend, he should be aware of it. If he has not "figured it out" then she did not communicate the fact that she no longer wishes to pursue a romantic relationship with him and she should do so. Since you are now seeing this girl, you should ask why she would not clearly communicate this to him. This could indicate that she is afraid of confrontations and would even lie to avoid them, or that she is not ready to burn that bridge with her ex-boyfriend as she might go back to him. It could even mean that she is someone who is not truly interested in either of you but is instead interested in getting attention. In any case, you should speak to her directly about it. If you see her ex-boyfriend, you should definitely not discuss this with him because his relationship with your current girlfriend is not your business. Discussions about their relationship should only be made with the person you have a relationship with (the girl in question).
If you are a girl then yes maybe. But if you are a guy you should not be married If she has another boyfriend
