My (21F) first time which did not go well [FM]

I am 21 years old female. One of the redditors asked me to share my experience here by creating this alt account.

It happened 3 years ago when I was 18. Fall in love for the first time with a senior and he was VERY nice (he acted nice tho). He manipulated me like whenever we had a fight, I had to apologize. And as the relationship went on for like 8 months, he started to be more intimate like touching me every time and kiss me, asking for nudes, etc.
