Why do some boys have to be such big jerks?

Well girl, not all boys are jerks. Boys tend to act differently because they can't easily open up their feelings. You've been with him for three years already with three huge break ups and you're complaining to why he's like that, why would you give him chances anyways? If you can't handle his attitude then break up with him. Acceptance is a need for a successful relationship, why bother being with someone whom you would think as a jerk? That word can be very foul girl.

If a boy has thin body and decides to have some bodybuilding, will you tell him to sacrifice his bodybuilding and spend time with you instead? Ok if that's what you want him to do then he will say fine -- no bodybuilding.. Just don't blame him later when he can't carry a sack of rice or a huge container of water or fix his car. Women should know that whatever men do it is for a future benefit.

We're not jerks. That's very judgemental for you to say and it's very offending. Don't you ever think that he only thinks about himself cuz he cares about you? I know it doesn't make any sense but if you think about it, it does..

Yeah im a a boy to i think boys can acting like jerks sometimes and girls are much smarter than boys.Boys just take everything very casually but not all are the of same type.

There are times when people are just selfish. In a relationship both people are supposed to be caring about oneself and about the other. It needs to be equal. If one person gives and gives then they will be sucked dry and have nothing left to give. Men are considered jerks because they are not as good at relationships as women, hence they do not care as much or do not display that many feelings because society tells them to be macho. Women are better at relationships because they were inbred to care for the family. Men always just go off and find the food and feed themselves. If they are no longer hungry for one thing they will go off and find the next piece of meat. Men are just simpleminded, whereas girls think too much in general.
