Baby on the way and don't feel happy with partner?

Rhianna
I'm 22 weeks pregnant and I don't know whether I'm happy with my other half. We are engaged, and everything's been fine, he's been supportive etc he's been the best he could be.. I just don't know how I feel anymore.. He's already got a son which sometimes makes me feel pushed out but that's life.. I just don't know how I feel! Help advice ?
