No sex..

I'm 34+3, when I first found out I was pregnant I knew that things would change or be different. My body, being one of them. Have I gained weight? Yes, but I've gained a healthy amount so far. Has my belly gotten bigger? Yes of course but it's not the biggest I've seen. Have I gotten stretch marks? Yes, as much as I tried to avoid it.. they popped up on my boobs, my butt, and on my sides a little. They're not too much but I never worried because my fiancé told me and still tells me that he will love me no matter what and he doesn't care about stretch marks. Well if that's true.. I feel like we would've had more sex than just about 4 times the past 8-9 months, or maybe he would actually show me some sort of intimacy.. ive tried everything.. I'd put on some cute panties, shave to the best of my ability, and put on some perfume in hopes that he would notice and maybe be somewhat turned on but he doesn't even notice. I've even tried flat out asking him if he wants to have sex and I get nothing but maybe a giggle. I feel so digusting and unwanted, so unattractive and fat. I just lay in bed until he falls asleep and I cry. The only time I ever feel sexy is when I go to give him head, he sometimes even acts like he doesn't want it but I do it in hopes that he'll be attracted to me even for the moment. I want it to lead to sex but he finishes without any warning sign. I've even went so far as to watching porn and trying to pick up ways to improve the way I give head because I want him to want to have sex with me and I take my time and tease and kiss, then when he finishes and cleans himself up he comes back grabs the vibrator and lays there half asleep waiting for me to finish. So no it's not like I'm completely without pleasure.. but it's pleasure without any love or intimacy or even care. I just don't know what to do and I don't know who to talk to about all of this, I just needed to get it off my chest. I'm sorry it was so long.
