Confused..

I’m dating this guy.. It’s been almost 7 months.  He still hasn’t learned the word no.. I mean he never knew it. I try not to judge him for the past but he keeps acting as he use to. He wanted to have sex and I did too but I said no because I know I wouldn’t be able to handle anymore because we already had sex not that long before. But he decided to push and push and I never said yes. But I could have left…. I just know he didn’t really mean to hurt me but I feel so used…
