I cheated on my boyfriend.
I really hope you're kidding. Why would you cheat on him?
I can't handle this anymore and I decided to find a partner who would accept me the way I am.
It's good to recognize that you want something else in a partner then you are getting right now. Cheating was not the way to go though. You should have broken up before moving on to someone else.
I don't care that much about my relationship status and at this point I believe I am better off single.
There's nothing wrong with wanting to end a relationship or choosing to be single. What is wrong is cheating on your current boyfriend. Doing that is going to hurt him and give him trust issues with his future partners.
