Is it wrong to avoid relationships due to heart-break?

I won't go into full details because it's too much explaining. But he was my VERY first boyfriend that's basically been a one-sided relationship where I was investing time, feelings and love for him while it was NEVER reciprocated. While eventually admitting that I "wasn't his type" despite being in love with him and admitting that he never felt the same way towards me and to have someone in his life that he's more compatible with after wasting 7 years of my time. Telling me to "get over it" and only offering friendship which I declined with him calling me "selfish" and gaslighting me for refusing to except his friendship offer knowing that I have strong feelings for him. Leaving me feeling hurt, used, discarded and FOREVER scorned which he blames me for my feelings as if I forced him date me against his will.

He never showed no remorse for me at all and I did nothing to deserve this treatment after so many sacrifices I've mad to be with him which he obviously didn't appreciate.

I no longer believe in karma because he is still out living his life and is happy as if nothing ever happened while I am still hurt. If something bad were to happen to him, I will not be sad or feel bad for him at all. So if anything this lesson has taught me was to never trust anyone else again as I will never get into another relationship with a guy because men are very heartless, selfish and evil. And they don't give a fuck about a woman's feelings at all. I am scorned for life and I will never trust anyone else with my feelings.
