What does it mean if you sleep with a boy and he breaks up with you?

Answer 1

He was probably using you, or cheating on you. Males like to have sex, they do not necessarily like long term relationships as much. This is a constant source of friction with females, who also like sex but who would usually prefer to have it in the context of a long term relationship. This is a very understandable consequence of the biological fact that it is the females who get pregnant, not the males. When raising children, it is useful to have a partner to help.

Answer 2

It could mean that he wasn't looking for a serious relationship or that he may have lost interest after intimacy. It's important to communicate and understand each other's expectations and boundaries before engaging in physical intimacy. Remember that your self-worth is not defined by someone else's actions.
