if she has been seen or anywhere near Jackie chances are that she has/is cheating on you...all lesbians fall for Jackie...maybe its the fact that she could pass for a man..maybe its the fact that she has been a hardcore lesbian since diapers..whatever the reason...if you've seen your gf with Jackie...i would just move on
ask her and tell her not to lie or you could just breakup with her and move on.
You can tell for sure that your girlfriend is cheating, by catching her on the act with her lover.
stalk her
'I'm bisexual'
Yes you should tell her that he is cheating. Because later, it will hurt her if not told.
One way to try to tell if your girlfriend is cheating is if she's refusing to spend time with you. If she has a new boyfriend she may want to spend less time with you.
you can't. just have to trust her, dude.
tell her.
There is no test to take that will tell you if your girlfriend is cheating on you are not. Girls all act differently and the fact is she is either cheating or not and no test can 100% tell you.
be as honest and sensitive as possible and make sure that you have proof that the person was cheating
Your girlfriend's cheating
You cannot tell absolutely except by catching them together.
