I find that girls like guys that love their moms (unless they Are the rebellious type) but you can over do it, make sure that the girl knows you care for her more than you love your mom, it may sound harsh on your mom but someone has to drag you out of the house and moms generally want their kids to stay for way too long
There is a difference between loving and respecting mom and being "Mama's boy". Some mothers can manipulate, cause problems. Other than that, a great relationship with his mom says a lot about the guy, and his mom. All good.
I experience this with my girlfriend of 5yrs. Even when my mom was almost dying then through recovery in hospital, she got so angry, a very cold attitude and chip on her shoulder towards me through this difficult time. The time I make to spend with my mom or help her on things is extremely limited. She wouldn't even ask me how my mom was doing while she was ill. Btw there's no feuding between them, nor a shread of clingy-to-mom thing with me. In fact I feel bad that I really don't go see and talk with her enough. BUT!!! My girlfriend is engaged with her mom and dad daily and very frequently. Very tight clickie and in each others business way too much for my comfort. It's strange she doesn't realize how that makes me feel and how its so irrationally unfair. My girlfriend is a good woman and I love her very much, but she is a classic case of irrational jealousy and chip on shoulder about her man and his mother :/ My mother is who made me the good man that I am that my girlfriend admires so much about me. So this is VERY confusing.
