I think you guys are misunderstanding Gal.
He is a player for the most part.
Gets with women for sex.
Not planning on building a long-term relationship, possibly leading to marriage and kids.
He invests very little emotionally.
So if the bitch decides to act funny, or sleep around, then he has no problem dumping the bitch and getting another one.
I think the guys taking offence to what gal is saying are the settle down, love you forever, and make babies with you type of guys.
Ofcourse in that situation, you would care about this type of shit way more than a guy like Gal.
