Can I have everyone’s opinions

Me and my ex boyfriend are expecting , I have blocked him because I caught him cheating on me with MULTIPLE females and after I put him out and two days later he was riding around with the first female I caught him cheating with ANYWAYS he claimed he wanted to be apart of the babies life but since we argued he’s made NO effort or attempt to reach me I unblocked his number just to see if he would text me ... and nothing . He knew I had an appointment today and he could easily reach my Bestfriend to leave a message for me . And neither that either ... am I wrong for not telling him or allowing him to attend my ultrasound or be apart of the babies life ? The girl he was with is on pills really bad !!!
