I am writing confessions of a cheater and his insecurities.
That's interesting. What are some of the confessions you would write on the blog?
Something that bothers me the most about my current girlfriend.
It sounds like you're remorseful about your cheating on your partner. It's not a right thing to do, it'll be devastating to your partner.
I am not really remorseful.  I only wanted to share my stories with others.
Well you should be remorseful. It is wrong to cheat on your partner because you are betraying the trust that she has in you. You could also be giving her a disease.
