I often observed that boys get bored quickly and look for breakups... while girls prefer to stay with the same guy for longer... whats your say?
Too much of an unair generalisation. Although what ive been learning about in psychology about parental investment is subtly linked to this. Eg- women being more concerned with the quality of mate and his resources in the long term, whereas the males compete for the sole task of fertilisation. But of course, things have evolved, and men and women invest equally in modern society. Things arent as simple as what you claim.
It makes sense looking at evolution and how it was to mate back then.
