Don't know if I'm still in love!

Has anyone ever experienced the feeling of falling out of love with your SO once pregnant? I hope it's my hormones but I picture myself doing this alone and I'm okay with it. We are engaged but I can't see myself getting married any time in the near future.

I'm not attracted to him, I'm not affectionate.

I don't know what to do!

Will this feeling go away? Will the love come back?
