Relationship changes

Hi guys

I am 19 weeks pregnant (almost halfway there! Woo!)

Anyway, long story short prior to meeting my boyfriend and future sons father I was married and divorced. Now that we are pregnant everyone has pushed us getting married on to us which has caused total anxiety to me because I’m totally not there. BD does know I’m not ready I have communicated that but it almost seems like we both are pulling away from each other. Has anyone else experienced that? Is it just hormones or could we really not be right for each other? I’m trying to work through it but the more I think about all of it I feel like I’m pulling away further myself. It’s almost like two people cohabiting in one house for the sake of the kid.

Any advice?
