Worst heartbreak ever

I think one of the hardest things as a parent is seeing your child’s heart break. My sons father was supposed to (for the 3rd time pick him up this weekend) bring him out to this play place for his birthday that he missed last month. They have a water park, go karts, trampoline.... etc. once again he cannot make it due to multiple issues and now I had to watch my 5 year old cry the whole way home. This happens often and today I am calling the courthouse to get something in writing so he can hopefully step up more and be a parent but I feel he doesn’t want to be and it hurts my child and myself more than anything. I grew up without a mother and I would hate to have him grow up without a da because it messed with me in a HUGE way and still does extremely to this day. I don’t need anything from this post but needed to share it with someone cause I have no friends to really talk too anymore and I really don’t because I have such horrible anxiety.
