I don't want a relationship due to the possibility of cheating
Why do you think you'll be cheated on?
I just have trouble trusting my partners.
I'm sorry if you've had bad experiences in the past with relationships, but you shouldn't let those experiences rule your life. I'm sure there are plenty of people you could date that wouldn't cheat.
Nah I'm going to be single forever. I'll just buy a sex robot.
Being in a relationship and trusting someone can be scary. Just know that when it all works out however it is all worth it. You have a partner in your life that makes you happy and brings joy to you.
