Should I block my unborn baby’s father who only watches my social media?

I'm currently almost 8 months pregnant with his baby. He knows and not once has he actually responded or reached out to me. I've tried to contact him by phone and he ignores me. I know where he works and lives but I'm not going to just show up there. It's 40 minutes away and I don't feel the need to make that much effort for someone who's not being responsive. He does stalk my social media though. Every time I post, I can see that he has viewed or liked my stuff. I know that he can see my growing pregnant belly and ultrasound pictures. He stays silent other than watching and liking. Should I just block him at this point and see if he reaches out via telephone?
