Tell him to stop committing incest ;). But how is she like his mom? Appearance, behaviour, or does she actually act like his mom and tell him to clean his room? I would subtly tell him what you think, without outright accusing him of having mommy issues.
A lot of guys actually go for girls that are like their mothers.
It's quite normal for a guy to be attracted to a girl who is like his mother. It works vice versa too. There's that saying: men marry their mothers and women marry their fathers.
Who remembers that scene from the Big Bang theory where Leonard's mother (who's a psychologist) tells Leonard that if he wants to sleep with Penny he should find out what type of cologne her father wore (and wear it himself)http://www.youtube.com/watch?v=LTI0eF-WuMA
@ 2 & 3 I've heard of that too. Only, I hope I don't marry a guy like my father...
Yeah I really wouldn't want a girl like my mother.
say to him, "You're boinking your mom, bro"
Yeah, my sister married a guy who is so much like my dad, it's crazy.You're friends with him. Just tease him! If it really gets to him, stop, of course, but... I'm sure there's a chuckle there or two. His mom was probably a nice lady, otherwise I feel like you would've described her as being horrible in your submission.
if you're his actual friend, and not some acquaintance type of friend, then you should be able to straight up tell him...
I would have no problem saying "she's exactly like your mom" if it were a closer friend.
Although you shouldn't have a problem with telling him this, it might weird him out, especially if he starts seeing the connection. Could you guys honestly see a strong resemblance between a parent and your SO and still be intimate with them? I don't see any resemblance between my bf and dad (thankfully) but if someone pointed out examples, I would be really weirded out and turned off. If he really likes this girl, maybe just say "she's nice" or something lol
^ Shit I was just going to put that. Son of a bitch.
