#1. He Doesn't Do What He Says He Will
Yes, it's true: You usually have to ask guys about 10 times before they'll actually help you put in those bathroom shelves -- that's typical. But when he promises to go with you to a friend's party and then bails or doesn't call when he says he will, that's a problem.
#2. He Keeps Asking You, "Are We Okay?"
Let's be honest here: Single men hate to talk about relationships. So if he starts suggesting weekly powwows, take notice.
#3. He Makes You into the Bad Guy
Your guy starts constantly choosing his buddies over you... and yet, he says you're the selfish one. It's called deflecting.
#4. He Makes Comments About Attractive Women
Look, no guy is stupid enough to go on about how sensual some random chick is in front of his girlfriend... unless, of course, he's trying to be inconsiderate.
