my husband is an asshole -long post!

So I just had my IUD removed last week, and I am so excited about potential baby number 2. My husband and I have our son together, he will be 3 in dec. 2017. So we were ready to continue building our family...or so I thought. My husband just got switched to day shift after working over night, 5pm-4am most nights, and we thought that would help our relationship also. However since he's been home after work, and since I have been bombarding him with baby talk, he has been so incredibly rude and mean. He scolds me every chance he gets for the littlest things, and rarely wants to have sex, which makes me think he really doesn't want to have another baby. He recently had weight loss surgery(nov. 2016) and has lost over 150 lbs. I know he feels great, I think he looks great, and I am so proud of him. I am still a pretty big woman, but he says he loves me regardless of what I look like. I think between the weight loss, the schedule change, and being anxious about another baby has made us resent one another. I feel like he hates being around me and could care less if I'm here. Sorry for the rant I am just so over feeling this way, unwanted.
