Why does she do this....!!?

Shes using you... and im speaking for expense I very much regret. I had my daughter at 19 and lived with my mom until my daughter was 7 months old. I still acted like I was 14 and my mommy would take care of me. I needed to learn that wasn't the case. I was now a mother and needed to find my own way. I moved out when my husband and I got married ( he was at college when I lived with my mother) Me moving out was the best thing for my mother and I. It sure was a shock at first to not have some one help take care of the house like my mother did. Ive now apologized to my mother many times adn she knows I understand what i did was wrong. Im sure my kids will do the same to me even if they dont have children in the house. Once you have children you do need to step up and do what is right. You are letting her live with you out of the goodness of your won heart. Not becuase you have to. let her know that. She will prob say she will leave, and you will regret it. Tell her you just need her to grow up and act like the adult her children need. I am now 22 and we have our daughter who is almost 3 and our son with is 4 months old. My mother now comes and visits us and get the star treatment becuase she deserves it.
