I wouldn't, but it is normal. I think you should give him a chance unless he is a jerk and treats your sister wrong.
Try being friends! Or go petty and kill the boyfriend.
Are you the person they were cheating or was it someone else? If someone was cheating you, I would say I didn't want to be their girlfriend (or boyfriend if you are a guy) anymore and that I saw them cheating. If it is someone else that was being cheated, I would tell the person who is being cheated and tell the person what I saw the person do.
I would end the relationship because someone that really loves you would not put your well-being at risk, but would do everything they can to help protect you.
By finding someone nice who likes being with you and doing things with you.
A boyfriend is a romantically favored male. This can be someone you are dating, or just hanging out with. There does not have to be any physical intimacy (sex) involved. A lover is someone that you are intimately involved with. You can have a boyfriend without him being your lover, but it is assumed that if you have a lover he is your exclusive boyfriend.
She needs to make a decision on whether or not she will keep threading her boyfriend on EVEN though she is in love with someone else AND if she thinks a long distance relationship will work with her lover. Lets face it, she's not being fair to her boyfriend by being with him but loving someone else.
What do you mean being caught by whom? Well if you're going to date someone but you already have a girlfriend or boyfriend, i suggest don't do it.
Yeah... IT'S NOT A LAW!!!
I would encourage my daughter to find another boyfriend if he is being a jerk in any form. Calling "ex's" is being a jerk.
im going though a emotion of hell here at home and need some legal advice. can i move in with my boyfriend, me being 17 and him being 23. my parents will not let me go anywhere because of my sisters mistakes. i would still be attending school.
tell her to get over it get some help talk to someone you trust and try and ask your boyfriend why he's being a doofus and talk to your friends about it, maybe someone whos had this problem before
I don't think that your boyfriend would be too happy about being "Beiberized" that's probably the last thing that they would want to happen to them!
