I understand and although I'm not joining you right now, I feel like I could come to that point if I'm not pregnant within a few months. It's all a lot to carry on your shoulders, on top of everything else. You will try again when you are ready, and honestly, it will feel probably be a relief to take a step back for a while.
As far as the comment by your DH, I know it hurts b/c my DH is also brutally honest and always has been. I've always told him I wanted him to tell me if I started to gain weight or "let myself go" in any way. I did gain about 5 lbs when I got pregnant and after the miscarriage I was in a state where I didn't care what I looked like so I kept eating and eating. My DH finally told me jokingly but seriously at the same time that I was carrying a little "junk in my trunk".. and I got mad at first, but then he reminded me that I said I always wanted him to be honest and he wants me to do the same. So I told him we needed to trim his back hair

but he got his point across and so did I. I started hitting the gym the next day.
I'm not going to lie; it hurt pretty bad to hear him say that, but I also don't want to give him any reason to not find me physically attractive. I have only lost one pound but my body has firmed up and he's been very good about encouraging me and telling me my butt "looks rockin'".. so I appreciate his nice words and criticism.
Sometimes it's hard to take a step back and see yourself in your S/O eyes.. or anyone else's eyes.. but I believe it is a good thing sometimes.
Just try to relax and take it easy for a while! HUGS to you!
