"Women dangle the carrot of sex to get a relationship, guys dangle the carrot of a relationship to get sex"
I don't dangle and I don't really like carrots that much. We are not mules girls and neither are you.
Too many women are looking for "Mr. Right". Guys lose interest because a woman can seem impossible to please, or he feels he cannot keep up with her, or she flirts with other guys when they are together, or she is constantly chaning her mind/plans with him, etc, there are a million reasons to lose interest in even the most stunning woman, sweet or not.
Most real men, I don't know about "guys" but a real man wants to be a "kept man" and feel appreciated by one woman; once a "real man" finds a woman he is happy with, his hunting days come to a close. For a woman that is. Now he starts to hunt for a better job, better apartment, etc, so he has an opportunity to spend more quality time with her and NO I don't mean to "provide for her" like so many stone-age women still expect a man to do (it is the 21st century ladies and you are all supposedly "liberated" - so you pick up the check half the time - or all of the time, we have been doing it for millenia, your turn, thanks)
Let me clear this nonsense up for the ladies once and for all;
MR RIGHT DOES NOT EXIST - I KNOW BECAUSE I USED TO SHARE A HOUSE WITH HIM, SANTA CLAUS AND THE TOOTH FAIRY AND ONE NIGHT IN A RED-FACED RAGE INDUCED BY A CUTE, SWEET WOMAN THAT WAS IMPOSSIBLE TO PLEASE, I ROAMED FROM ROOM TO ROOM WITH A SHOTGUN AND BLEW THEM ALL AWAY.
Grow up ladies, stop looking for Mr. Perfect, he was a wrestler in the early 90's and he died of cocaine and steroid abuse.
Start looking for Mr. "Just Right Enough" and go find happiness together.
