I'm jealous of my boyfriends relationship with his mother?

^lolwut?

Having sex dreams about his mother is way too far. Did you ask him what the hell is wrong with him? ha, There's something strange going on here. Especially for the mom to be acting flirty??
I think you need to get to the bottom of it (his feelings) in a nice way or drop him. "Man of the house" doesn't mean he needs to play her "husband" role also.

taking over the house after the death of his father is a very noble and mature thing to do. however, having dreams about intercourse with his own mother is not normal, at all. he is still her son. it seems as if the emotional trauma of loosing her husband is causing his mother to cross lines she shouldn't. however, i don't know you, your bf, his mom or the detailed story so it's hard to place an opinion based on the vauge scenario given.

You should suggest a three some

they are gonna have sex or they have had it already. He 's just lying to u bout dreamin n stuff. Talk to him . Leave him !!

My husbands mother did almost the same thing after her husband died. The difference was She made him feel guilty if he didn't take his ants down and let her look at his penis whenever she wanted. She even did it front in front of me to make me jealous

If he told u he had a sex dream about his mum then why didn't u break up with him

Your reaction is normal. The Oedipal dynamic you're describing is not. Even if you take that aspect of things out of the equation, it's a pretty base mammalian instinct to have that parent/suitor rivalry. It's not necessarily sexual, in the sense of 'sexy.' It has more to do with the parent being subconsciously concerned with what genes are mixing into their family tree, and the potential mate fighting for the privilege of becoming a branch on that tree.

^what's wrong with young people?

sorry i think even a man wouldnt have dared

its normal for her mom be like this. because of trauma and emotions and all. but to some limit. after all he is her son. but your bf is completely insane. i think he is out of control. what the????
he should be respecting his mom if he is normal. and moreover even though he has got a girlfriend????? its a normal manly instinct but its not sociable and acceptable in modern society.
he would have been complete macho in early times but not now. he is cassanova's master in rebirth. i would say he is not trustworthy at the least.
come to me. he he. just kidding.

Wow. Really? Not cool/normal

I think your imagination is getting the best of you.
He assumed the role of father of the house as a sign of maturity, and it's a familial duty. The dreams probably mean nothing. I'd say it's just his mind accepting the fact that he is now the man of the house and responsibilities lie on his shoulders.
You need to mature and realize that he is in a stressful position that was thrust upon him, he didn't choose it. It's not like he's choosing his Mom OVER you,he can have both if you grow up and don't look at him like he's a freak.
