<human>: Hey Guys,

I'm wondering how should I break up with my girlfriend. This is my first serious relationship I've been in. I've been dating her for two years and we always fight because of me. I am very forgetful about stuff (Monthaversary), and like I always forget to do things that any normal boyfriend would. She has to remind me to see her after I'm done my classes.( I know it's my fault since I don't remember.) She likes to know my weekly schedule in advance, and I forget to remind her. Or I forget to let her know what I'm doing that night. 

I've been trying hard to remember, but I forget sometimes and it just gets into a blown out argument. I say sorry and I'll try to change. But whenever I mess up, an argument breaks out.

I want to let her know that she's not the reason we're breaking up. It's me. She's a terrific girlfriend. But I'm just a terrible boyfriend.

Summarize the given text in a few sentences.
<bot>: Want to break up with my girlfriend because I'm a bad boyfriend. Want to do it nicely. How to do it?
