Momma's Boy!

Question: How do you all deal with a guy who's a mommas boy?

One that puts his mom first then you, one who never goes against what his mom says, and one that has tattoos of his moms name etc? A mommas boy that is 25 and up.

My fiancé is a mommas boy but I'm starting to feel some kind of way just thinking about my future I think this might be a problem but not sure if I'm over exaggerating.

Tell me your experiences and how you'be dealt with a man like this?
