Ask your boyfriend. If you don't trust his answer he shouldn't be your boyfriend.
i will not tolerate and i will leave that girl which is not mine..
I would say she is trying to make you jealous, or that she wants everyone to know she has the greatest boyfriend in the world, and she wants the world to know.
It mean's, she trust's you more than she trust's her boyfriend, or because she is shy around her boyfriend and she doesn't know how he'll react.
You should tell the other girl and both break up with your boyfriend.
The only thing you can do to be sure is a paternity test. It's important to get one, so you'll know
ask her
A girl wants a boyfriend to say he loves her by the way he treats her, in private and in public. A boyfriend who tells her by his actions more than his words. A boyfriend who shows her respect when with friends or family, in the presence of strangers, and especially when they're alone when no one else is watching. She will know that he loves her because he makes her feel good about herself.
she tells you
I know am not a girl, but my boyfriend is my sex partner.
When did he say these things? and are you guys dating? My opinion is that if he loves another girl, forget him. It's not fair to have a boyfriend who's "cheating" on you, even if you know he is.
Because she likes you and does not want to tell you or let you know because she is afraid you may reject her. There is no boyfriend or if there is not much of one if you like her go for it.
ummm askk her !
