Jump off???

So a guy I’ve been dating for almost a year, recently told me that I was “just a jump off”... but he said it in a insulting way as if he were saying “you think you’re special, but you were just that...” but however, he would send texts that made it seem like he liked me... he sent me voice texts that sounded like he was jealous & insecure... then acted completely normal the next day... he said he did it to get a reaction out of me.... I’m confused.... he sent long paragraphs in the beginning about how much he “was interested” of course this was all before sexual relations.. he was consistent in the beginning which I guess also makes sense... then after having sex more regularly, he started getting inconsistent and started ghosting me... conversations were almost always sexual only... he kept saying “I was a good lay” and “had good 🐱 “ but....... I mean..... I cannot tell if he’s playing me or he’s afraid of getting hurt.. (he was previously cheated on) he tells me that I make him nervous when we talk & sometimes I can visibly see his nervousness. He has panic attacks and shakes sometimes when he sees me.. (I figured it was like how women get butterflies) but now I’m just like.... meh... I can’t read you anymore... what do you think?

Because it went from always talking every single day & very detailed messages, (before we ever met) to just dry and forced conversations eventually... he kept trying to talk me into having sex with him which I denied him for several months before I agreed... now we’re at what I said in the beginning.
