snogging another boy.
The reason is because they are upset but they do not want other people to see them upset
Did you not know he had a girlfriend? If he was hiding it from you... i'd say slap him/kick him in the balls and let his girlfriend know what he did.
no there is no reason
First try not to get upset, understand she's think that way for maybe reasons you showed her and do your best to prove your doing absolutely nothing wrong, if she gets upset try to ease her down. People think better when there calm. Just don't try to get upset with her if you do there needs to be a reason why she's thinking that way find out then do your best to fix it.
Most likely unless she really does not like you.
You maybe doing something wrong to make her upset.
YES!!!!!!!!
