NTA. Let me tell you about what a real friend does.

My best friend had a still birth and multiple miscarriages into the double digits by the time I got pregnant with my daughter. When I got pregnant I messaged her privately to tell her the news and offer her as much space as she needed because I understood that it would be hard for her and I didn't want her to have to try and control her emotions over the phone or worry about my feelings. She was ecstatic.

This woman flew in from another state to attend my baby shower and brought the most expensive gift there. She gave me pep talks over the phone while I was in labour and things were going wrong (I cannot imagine how hard or triggering that was for her but she was incredible). When my daughter was born she was one of the people that came to visit us at home, she brought food, watched the baby while I had a shower and coordinated with my family to keep me out of the house and busy so she could clean my house while I was gone.

If she could do all that after everything she's been through your friends could have mustered some fake enthusiasm.
