Hate sex now

I was a single mom of a 1 year old when I met my husband. We had great sex but a year later, before we got married I found out he was watching porn. (Something he brought up and said was considered cheating so we both agreed not to.) Before that I had asked if he was attracted to me still because he stopped having sex with me. He said "well no one likes fat." That really hurt but I did weigh 152 at the time. After that comment I worked out very hard and eventually got down to 128. We will be married for 5 years in June but our sex life has gotten way way worse. He said working out would be a turn on so I do it but it doesn't change anything. He hardly has sex with me, hardly touches me and rarely tells me I'm beautiful. I've talked to him about it but nothing ever changes even though he said he will have sex more. I try to give him head but he says no, I try having sex he says no. I try to spice things up, wear lingerie, send him sexy pictures. I workout, eat healthy, clean the house make him his lunch because I know doing the house wife work is a turn on for him but yet it doesn't seem to be.

I feel so depressed about this and I don't ever feel like it will change. I just want sex a couple times a week and I'm lucky if I get it one time. I'm to the point I hate sex and don't want to have sex with him anymore. I want to play hard to get but than we would never have sex. I feel like I'm only here for his convenience because we only have sex when it's a good time for him. I'm so mad and hurt. I want to start pleasing myself and not have sex with him anymore but I know that's wrong.

Sorry this is so long I just don't have any one to talk to and I don't know what to do.
