My best friend is upset with me because she has been stressing me out so I told her I don't want her at my next appointment. She is making a big deal about my childs father not buying anything yet when we don't even know the sex. When I had to move and couldn't find a place she didn't offer for me to stay with her. She hasn't bought anything. She has also only been to 2 appointments. She is pissing me off and stressing me out like it's her baby. I need the father there and want him there and nothing anyone can say can change that. I don't care if we're together or not it's his baby and he wants to be involved. I won't keep him from his baby and I shouldn't be punished for that. She hasn't done anything but stress me out more and at the end of the day I need family and my child's father over her. I'm so torn because I feel like a real friend wouldn't give an ultimatum especially when family and the father should be there over friends.
