Hormones are killing us

39 weeks pregnant and I feel disgusting, my hairs grown out, I've gained weight obviously and in my face, I've always been really self conscious.....especially when it comes to my husband, before me he never could hold a girlfriend...he said he's never cheated on anyone but instead hadn't been with anyone longer than a couple months at a time, he was never good at being alone....
Well last night I saw a post in a Facebook group we're both a part of, a really attractive, skinny blonde posted it, I looked at her Facebook and saw she lives near us but had no mutual friends to us....I joked to myself that he would probably add her by morning....woke up this morning and lo behold all of a sudden they're friends on Facebook.... My husband has pics of us and his status is married....I guess it just bothers me because she's everything I want to be again, and I knew he would be attracted to her and add her and he did....I can't stop crying over this and I feel foolish.... Yes not very controversial but I trust your guys brutally honest opinions more than those who will just baby the situation in other rooms.....
