About to snap!

I'm literally about to lose it. I'm 20 weeks along and I can honestly say this pregnancy has been nothing but unenjoyable. I've spoken to my baby's father 3 times since I found out in March. He decided that he wanted nothing to do with me, the pregnancy, or the baby. When I went for the anatomy scan, he told me not to even bother with telling him the gender. He has changed so drastically in 4 years it's insane. I literally have cried every day of this pregnancy. I'm hoping he will change, but I'm not counting on it. If you have a SO that is involved with your pregnancy, don't take it for granted. I never pictured mine to go this way and I'm honestly exhausted from trying to be strong.
