Should I leave?

Basically our sex life is HORRIBLE. Our communication? Even worse.

I have done EVERYTHING to please my partner sexually. I know he loves blowjobs so I used to give them DAILY for 2.5 years. Now he gets a blowjob every 2-3 days. I have dressed the way he likes, wore the lingerie that he likes. I have always believed that it is my duty to give my partner sexually everything he wants, and try to fullfill his every fantasy (that I am okay with). If I was with ANYONE ELSE, I feel like I would have been seen as a queen.

After a while, I realized that I don't get what I want. During our 3 year relationship he has barely touched me. And has returned the favor at most around 7 times. We have tried communicating and he used to get angry at me for even asking him to put in more effort to please ME.

Lately, we have both given up. We never had chemistry, bad that doesn't mean we weren't extremely compatible (life goals, values, etc). I am so MAD!

What the F@#$ does he have to complain about? Sex has always been about HIM, no matter how many times I've simply wanted to at least reach an orgasm! I am not hard to please, it takes me VERY LITTLE time and effort. But sex always stopped as soon as he was done.

You can see, over time I simply didn't want to do anything sexual with him. I felt used and abused. He, is never ever pleased. He knows how much effort I put into his sexual pleasure, yet he is apparently miserable with our sex life.

I am so MAD! How can he be miserable? I have been completely honest with him and he knows what I want, but refuses to put in actual effort. Now he keeps saying how miserable he is, and how I can't give him what he wants (even though he admits it's not my fault).

F@#$ HIM!
