Well my friend, same thing happens to me, but wanna hear what's really funny and worse? Sometimes in order to stalk a guy, they call my number and ask about the guy, or stupidly give me missed calls, I just tell them to leave the person in peace. When it is too late, then it is too late :)
Sods law. Same for women though.
When someone was alone they may have not been as happy as they could be because they were lonely but when they find someone to be with they put out a happier type of energy and that attracts other women.
Women prefer men who don't appear desperate. Many of us also want what looks to be out of reach.
Same for women :-) x
