Would you be upset?

So me and my children’s father broke up about 6 months ago and I’m due 2/1... last night he tells me he’s going to Virginia 1/24-1/27 (we live in MA) and all i said was hopefully the baby doesn’t come while you’re gone and he goes “yeah hopefully, if he does i won’t be here” basically saying he could care less... he’s had so many months to go visit his family and didn’t want to or “couldn’t” take time off of work and waits til the very last minute meanwhile I know his mom paid for his flight and idk why she would even think it’s okay when she knows the due date... this is also the same lady that took it upon herself to do a DNA test on our first born WITHOUT my permission so i don’t put anything past her at all! I’m upset about it but there’s nothing i can do!
