First, some back story I've never been close with my dad until recently. My mom raised me and we stuggled for money while my dad got married and had a new family with plenty of money. This is going to be the first grandchild on all sides.  My dad has been asking to go to the dr with me and it's not something I'm 100% comfortable with but I was going to let him go anyway to make him happy because I thought he was excited to SEE the baby. 
When he found out I was doing a gender reveal this was his response... Keep in mind I my husband and I are not finding out until the reveal party. 
The last message was on Father's Day, I completely forgot what day it was I had been working on cleaning out the future nursery all day. I feel like if I had forgotten any other time he wouldn't have said a word. I'm allowed to forget things right, I'm pregnant after all. 
I haven't responded or spoken to him because I feel like he is just looking for a fight. I've been really stressed out at work and I'm trying to eliminate as much stress as possible. At the same time I don't want this situation to get worse. 
Please share your thoughts and feelings, thanks.
