Am I being petty???

My husband and I have been together almost 8 years. We have a 3 year old daughter. We've had intimacy issues for probably close to 2 years...not so much on his end (I don't think although it's questionable...but I'll get to that in a minute) but more my end. It's not that I don't want it...but in all seriousness, since we've been together, I've gained about 100 lbs. Mostly due to depression... Now, he's still all about wanting to have sex but I'm not sure if it's due to he has needs or what. I question him, because he's called me a series of names the past month that have driven my depression into overdrive (I emotionally overeat or stress overeat) The names he's called me are: Fat, nasty, 10 layer bitch, hippo, that I looked like a sack of chewed bubble gum, he wished i would die so he wouldn't feel guilty about wanting to leave me because of our daughter. Each time after he's said these hurtful things, the next day or even several hours later, he acts as if nothing has happened and wants sex. The last time he did this (2 weeks ago) I've flat out refused. So much so that I've even slept in my daughter's room. He gets angry because I have been. I've told him that it's no different than when he wakes up in the wee hours of the night and goes to sleep on the couch when I've slept in bed with him. He doesn't seem to understand this. Anyway, last night he went to bed around 9 and I decided to sleep in my bed too. I went to bed around midnight. When I woke up around 3 a.m He wasn't in the bed, but on the couch. Here's where my question comes in..... I told him (in a text) that I guess from now on I'm just going to sleep in our daughters room since I gave it a go sleeping in our bed and he still decided to sleep on the couch. I'm just really exhausted trying to "prove a point" or hope that he sees or realizes how much he hurt me with his words and actions.He thinks I'm holding onto this as an excuse and I'm not. I've told him how bad it hurt me, how it made me feel. He seems indifferent. he apologized it it didn't seem heartfelt. Just seems like he said it to shut me up. I just can't let this go this time.
