Need to vent.! long post sorry

Okay, so me and baby father not together anymore. We planned this pregnancy and everything and no longer together yeah it sucks I know.!!!!! 
Anywho he cheated and I wasn't okay with that so we called it quicks. Yes it hurts like hell but I deserve more respect then that and on top of that I'm pregnant with your child you owe me the upmost respect.! There so much more to this story but really don't wanna go in detail.!!
Anywho fast forward to today.!!! I went and got my ultrasound to find out baby gender and I had them seal it up so me and baby father can open it together. 
So now a lot of my "friends" and "family members" are mad because I'm involving him in this experience. Even went as far to say "only reason I'm involving him is because I want him back and I think that'll make him want me" 😒😒 so that pissed me off.!!!
My view on the whole situation is what ever personal issues me and the baby father has going on is between me and him and not the baby. So yes he wants to be involved and he wants to take care of his child so why wouldn't I let him. I have no reason to be spiteful towards him when it comes to the baby.!
Yes I'm hurt and heartbroken but I'm also a very mature woman and I know I can get through this but I will not let my hurt be involved with my parenting (if that makes sense). I don't feel like I need to use my baby as leverage to have him around because we planned the baby it wasn't an accident I love my baby with or without him and more then ever I love myself to know I don't have to settle.
My big thing is everyone wants me to be spiteful and mean and bitter to him and I have no reason to. Everybody wants me to show my hurt to him through the baby but I'm not that type of person and I refuse to be. But what hurts more is that the people who know me thinks I'm using my baby to keep him around.! I've never been that type of person.
