She might. It depends on the individual.
Anything your girlfriend (assuming you are a guy) would not want you doing with the opposite sex. Basically, if you are doing something with someone that you would not do in front of your girlfriend, then you are cheating. Cheating has to do with violating your girlfriend's trust. Some girlfriends may not care if you give another girl a massage, while some may. If your girlfriend is in the latter category, then you are cheating if you do it.
On a holiday, you would want to spend time with your girlfriend. And if she is cheating, she'll refuse to show up. That is one way to find out. Also, her weird reasons for not doing what you usually do, can imply that she is cheating.
no because then your girlfriend would be cheating on you with your friend and you will be mad
Leave her without violence!
Who made her pregnant? Did you? The answer to this question will go a long ways to helping you to decide about your future with her. If it is your child, you have a dilemna because you are responsible for support. If it isn't your child, you may want to leave.
Unfortunately, condoms are not 100% effective. You can get pregnant while using one. I know this from personal experience. I would suggest, if you have no reason to think that she was cheating on you, that you start to think about the life you have created, and the best plan for that child.
Only if they don't know about it. I would ultimately depend on the terms and conditions of the "relationships" that you are in. If you are their girlfriend, then most would probably consider this cheating.
he probably wouldn't if he i smart, but dumb people would. they also would be cheating on their girlfriend. DO NOT CHEAT ON YOUR GIRLFRIEND/BOYFRIEND. EVER! thanks for reading! bye! (P.S i am draggonessclaws101. ADD ME! :D)
No it isn't but as i am a girl and another girl put her head on his shoulder i would flip out but its not cheating! x
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 don't think I would! I mean she has to earn your trust back. Otherwise you wont have a good relationship if your worried shes cheating on you all the time =[[
I would say that it is definitely a possibility. Even if he is not or has not physically cheated with her he is emotionally "cheating on your relationship.
