OK ual question for s only please.....Kinda long though...?

First off I have been dating this girl for over a year now I love her with all my heart and I believe she does me too . I am starting to get bored with her all she wants to do is drink I want to have fun as well but I don't think she relizes you don't have to drink to have fun right? Now the other part I have a four year old I have'nt always been with just women I could'nt but when my mother ped away 4 year's ago I could finally be with who I wanted to be with.. But she is constantly throwing in my face that I am going to go be with a man that I like them cause I have a child ect. so on and so on.. WhaT CAN i DO TO EASE HER MIND? And yes she was with a man one time wien she was a teen she is now 35. The worst part is I moved from a hole nother State to be with her . I don't know anyone here except her friends and family.. Who do I turn too when things go wrong? Where do I go? What happens ? I really need help to these questions... Please
