Time to call it quits?

After three years, the last few months have been questionable. I used to be affectionate and when I noticed that it wasn't being reciprocated, I pulled back. He's just now noticing and in turn has become more annoyingly affectionate. He doesn't make a point to remember important things like my birthday or our anniversay and it hurts. I still feel tears and jealousy knocking when I see people ( not celebrities, real people that I know)posting sweet things that their s/o has for their anniversary or just because. I used to wear cute bra sets and lingerie to bed and he'd take them off and fling them on the floor, not giving them a second look or thought. I've stopped months ago and he's just now noticing, claiming that he's never seen me wear anything. I'm naturally shy and awkward and he tells me to be more sexy(even during sex), be more social, be more this and that. I've made minor adjustments on the social end but I told him that it isn't going to happen over night. Not once have I asked him to change anything but maybe use air freshener after using the bathroom. I would write him long messages that he could wake up to and feel good about, he's sent me one recently and I didn't even care about it anymore. We used to get along so well like saying what the other was thinking, we rarely fought, communication was pretty solid, we'd have sex three times a day and I was sure that this was the man that I was going to spend the rest of my life with. Now we fight quite a bit, we barely have sex and there's a huge disconnect. He's doing things I asked or communicated to him too little too late. He's been saying hurtful things and this past weekend he was telling me a story that he's told me before, didn't like my reaction and asked me if I was raised by wolves. I used to be excited to see and spend time with him but I couldn't wait for him to go home. I love him to death but he's not the man that I fell inlove with. I'm not saying that I'm a saint but I've been a damn good girlfriend.
