As a man I was taught how to treat women, I was never taught how a woman should treat me. Is this normal?

I know this is crazy, but damn. I had to learn basic shit about respect, reciprocation and basic kindness from coworkers. I was never taught what disrespect was from women, I kinda stupidly fell in love with my married coworker than gave up on love as for the last 10yrs it's not worth it. I've been rejected, used, verbally abused, told multiple times I'm not good enough and I'm just done with women. I'd rather die alone at this point. Soo much pain for nothing. I had a coworker she told me as someone who knew her husband since grade school and were married for 10 years and has 3 kids it's not worth it.
