Angelique • Can't wait to be a mummy

So my baby girl is 12 days old today, me and her father were never together we started talking met a few times and one drunken night lead to me getting pregnant, he’s done a DNA test due to the circumstances, and we are waiting for results (due at the end of the week) Since my daughters been born he has shown so much interest in me and her, constantly asks how we’re doing and wants photos of her, I don’t know if it’s my hormones but I feel like I’m falling for him... what do I do??
