So, did I just do a toxic thing?

I met a guy at a party, we had a lot of chemistry
we met up a month later when I was in town
we had amazing sex, great performances on both our parts
He showered after and that’s when I left, I didn’t say goodbye I just left.
he messaged where am I and I said
‘I’m no good at goodbyes, you needed a rebound, so there you go, I like you but I’m not getting involved with a guy that’s just broken up with someone, it’s hard’
So, did I just do a toxic thing?
