<human>: Judging by the title, this whole thing seems pretty petty, and it probably is, I just need some perspective. We only dated for three months and he broke up with me a week ago because he "couldn't give me what I need".  
Anyway, today he contacted me asking how I was. I shouldn't have replied, but I did.  
We talked about the break up a little, him trying to justify things mostly. He finally asked if I would return some of his books and if he could pay me for the concert ticket I bought, because he didn't want me to waste money because of him. I said I would give his books to our mutual friend, and not to worry about the ticket. He then gives me the real reason he wants to pay, he wants to take his brother.  
Am I right for being offended? We got into an argument, and I didn't agree to give him the ticket. It's a really important concert to him, and if I don't give it to him he'll have to go alone. I feel guilty even though he mistreated me for almost the whole relationship. He also probably only contacted me because he wanted to ask for the ticket, and was trying to butter me up first. My conscience is killing me and I'm wondering if I should just give it to him. I'm in a lose/lose situation.

Condense the text into a few key points
<bot>: jerk ex asked me for concert ticket to an event we were going to go to, seemed like he tried to butter me up first. Feel guilty and like I should just give it to him.
