Here we go!!!

OK so my best friends younger sister has been with my son's dad for a few years now. To start things off she is like 6 months pregnant with a boy and on Thursday they got married. At first I didn't let things bug me but now that they are married and he is taking me to court for 50% custody of my son. It is all a little to weird for me. I have raised my son for 10 1/2 years with the help of my parents. I'm not saying his dad hasn't been in his life but just not all that much. I don't know if I could handle him having him that much. The thought of them 2 trying to make a happy little family with my son just gets under my skin. Don't get me wrong she is great with him and as a single mom that has always been my fear is that his dad would marry someone that wasn't good to him.
