Pregnant, in a relationship& and need advice!

I’m going to try to make this short and to the point... I’m 19, I already have a 9 month old and I’m currently 9 weeks pregnant with my current boy friend. We’ve known each other for 2 years but just started dating ab 3 months ago. So here’s the story. I have a dr appt next week and ultrasound scheduled. I’ve been so exited ab him being apart of this pregnancy and dr appts bc my first baby daddy ghosted and I never got to experience the dad being involved. Well he told me today he is gonna go to a volleyball game w his friend instead of the dr appts for the baby. I told him that I was upset and preferred he came with me. He told me I was being controlling and didn’t trust him. When in reality I just want him to be there with me to experience this... he’s literally always with his friends and plays fortnite all throughout the day, so he barely makes time for me as it is. I’m honestly upset rn. He told me he’s promised his friend he would go to the volleyball game and if I had a problem with it, I could breakup with him. And well... I’m honestly wanting to breakup with him. I feel Ike he puts everything over me and this pregnancy already.🤦‍♀️
