So my child's father of course can never have a simple peaceful conversation without switching shit up and having to make an unnecessary argument just to get out of something. He's going to tell me I can't go to a show coming to town in about 2-3 months, but he can. I told him I'll go if I please because he doesn't own me and the venue has accommodations for people who need them (I.e. Handicapped, pregnant women, etc). He's going to tell me it makes me look like I don't care and it looks bad so I tell him if I'm comfortable enough to go when the time gets here I will happily go because I don't know the next time I will be able to do something like that post baby with him not being physically in the house to help me out. He's only saying all of this to be spiteful and petty and then texts me saying don't expect any of the blood work my doctor told him he needed to get from him because he's not going to do it. I don't care about him not doing something for my sake but now you're going to be petty and drag the baby into it? Ohh no no no that doesn't work for me.
