<human>: I (25F) decided to take a break from my 5-year long relationship with 26M a couple of days ago. We decided a time to meet next week and I'm absolutely dreading it. 

To everyone here posting that the girl breaking up with them kept saying "I don't know," I can relate. That's what I was doing here mainly because I didn't want to hurt his feelings but I really just don't think I'm happy anymore. We don't have many things in common, we don't have the same sense of humor (he is very negative and sarcastic and puts people -myself included- down to be funny, I am positive and like cheesy puns he doesn't laugh at). 

He also did a lot of things in the past that really hurt me. He put me down and called me names and was verbally abusive. That was years ago, am I wrong for dwelling on it? He still does it but to a lesser extent.

He left a gift at my door last night and wrote me a letter about how horrible he feels to not talk to me. His mom even texted me! So I am really close to caving. 

But almost everyone close to me said that I am doing the right thing. So I'm torn.

There are more reasons for this that I wrote in a long letter, which I haven't sent. I don't know if I should give it to him. Everything just hurts so bad.
