Search Results: younger girls dating older men

A lot of women say that they prefer to date older men because they are less mentally mature than younger men (or maybe for other reasons but the point is that they prefer older men). But it would make sense to respond to my question with a yes since the whole point of dating older men is the mental maturity right?

I was on training for 3 months in a company where we met.
She was a sex addict before meeting me , she was involved with all types of men younger, older, middle aged and had sex with all of them,
i also felt she had bipolar disorder and obsessive thoughts about sex, my friends told me about her past so i was just stringing her along because i knew she liked me and i would never make such a woman my girlfriend or wife, i dint want to have sex with her because i feared catching any sex disease from her. Her self-esteem was also very low.
She used to have orgasms in office just by looking at me. (she used to open her mouth and used to freeze for 5-10 seconds while looking at me so i knew she is having orgasms looking at me)
She told all of her friends and sisters about me and maybe even planned a future with me.
Obviously i never dated her infact i started dating another girl, she found out and went on a sex rampage to get over me or something, she used to come to offices with bruises and love marks all over her body.
Even then , she used to look at me as if she can't get over me.
Now, i heard from a friend that she has comitted suicide and hung herself because she was in severe depression.
I am feeling guilty about all of this, I just played with her and told her i like her because I felt such women who have tons of partners are actually fun to play with and they have no emotions at all.
She was good looking and all but i just didn't want a woman who was a village bicycle that everyone rode on.
Was I at fault?
