I should have left you a lot sooner, and I'm sorry when I did that, I did so without telling you why.
Can you tell me the reasons for it now at least?
There were quite a few reasons for breaking up with you.
Staying in a relationship that you're not happy in is a bad thing and its good that you got out. Doing so without giving the other person an explanation is bad, however, and you should tell them why you left them.
I don't care what they think anymore.
It is fine if you don't care anymore. I just think that you should not stay in a relationship that you are no longer interested in.
