a part of me & my cats relationship changed after he bit me 😔 i kinda miss him being with me 24/7. idk what changed for him i dont treat him different

Maybe he associates you with a traumatic memory, you might need to spend some time with him just you and him, give him treats and play with them and smother him with affection. So that he remembers the good times.

Cats are territorial
You said (Cats)

Once had a (18lb.) Ragdoll who slept with me every night and kept the others away, rarely would he share me with another.
He didnt like my tossing and turning, so one night he left to sleep with my ex.

The others (four) came and took his place with me for a night. When he realized this he got furious and the next night chased them all away again taking back his spot with me.
Hehe...,he just learned to put up with my restlessness there after.

You a snack tho

That's why dogs are the way to go.
