Should I complain about my ex trainer touching my glute or leave it?

Honestly I was telling my friend about how I’m over the crush and I told her I guess it developed but looking back he was creepy.

he touched my butt once like actually cupped it and another time he was sticking his hands out whilst I was squatting and going “to there” “to there” and actively touching my butt cheek with his fingers other little things like grabbing my lower back during certain exercises my friend said complain. But I think it could be too late plus I did end up crushing on him so they probably wouldn’t take me serious
