Dear Wall, I’m the girl who’s discussed by my gf as being like a 3 yr old kid. ->quick response. I think this is just a form of atta-chment behaviour. no need for her to act like my mom. Thx for your response though.

If you know you are the GF in the earlier question, then you and your partner must be discussing the behavior mentioned. I am very relieved to know that you and your GF are being thoughtful and open about how your relationship is going. As long as that is the case, you will need very little advice from me or others.
