Standing up for yourself without feeling bad?

ab

I started talking to someone and he began to disrespect me.

He would constantly tell me to send him explicit photos of myself multiple times a day and I would refuse. He would message me and tell him to meet up and have “casual sex” at random places. I would leave him on read and he would still constantly message me asking for such things.

today I got tired of it.

I told him he’s not in control and I’m not going to put up with this. & if I ever got to the point where wanted casual sex, I wouldn’t play by his rules or little games. I would hit him up not the other way around. Basically, my point was, he can’t control me or disrespect me, I would be the one in control if I ever decided to get to that point (which is a no lol)

He proceeded to tell me I was the biggest turn off ever.

I have always been a doormat and got tired of being mistreated by people and have decided to take my power back.

Was I too harsh? I’m new to standing up for myself :/
