How would you feel if the father of your child left you when you were 6 weeks pregnant told you he wasn’t going to be your support through the pregnancy got a new girlfriend not even 2 weeks after and doesn’t mention he even has one and you found out through Facebook, only shows up to the ultrasounds he wants to attend thinks he’s about to be able to take the baby whenever he wants as soon as he’s born and then asked you at 25 weeks pregnant if you’d be willing to have dinner with him and his girlfriend so you can meet eachother?
