Was he playing with my feelings for validation? Did he even care?

Both 45 yo and divorced. We were in a situationship, getting to know each other. His brother in law is a mutual friend. For 4 minths we would text and videochat everyday. Every weekend he would have dinner at my place. We hang out at concerts a couple times. No sex (he has ED for years) and we could talk for hours like only a couple minutes went by. But when after 4 months i told him ILY and wanted to know what were we... he rejected me badly, saying he can't feel love, all he feels is rage towards his late marriage that ended 3 years prior. He said i was an amazing woman, although i should lose volume (i'm 75kg) and that it was for the best. He hasn't said anything since, its been 2 months, although he sees all my social media stories. I am hurt pretty bad. I started having panick attacks, i cry almost everyday. I feel like crap. I know he was in a lot of dating apps like tinder and his ex was not nice - she won't let him see the kids - but had an amazing body. Was he using me to validate his ego?
