<human>: I know it's not anything dramatic, but it bothers me each time I see him. My friend told me that he likes my close female friend whom he met only once before for a brief amount of time. He proceeded to ask me what my opinion is about it. I told him I don't think that's a good idea. He asked me to tell him honestly why. I told him he was a nice guy and it's not because of him. 
 It totally was.

I've seen how he reacted violently after his last brake up. In fact, he confessed that he will go back to her the moment she calls. And after that he expects me to give him my blessing? I don't want my friend to be used as a rebound.
I ended up telling him half truths and white lies about the bro code, and that I would feel uneasy if they start dating. In truth I don't think he will be good for my female friend, but I couldn't bring myself to tell him. I'm afraid that I would hurt him, but It's hard for me to be dishonest. It's fun to hang out with him, but I don't want him dating anyone I care about.

Can you condense the text into three sentences or less?
<bot>: Told a friend I would feel uncomfortable if he dated my other friend, but honestly I just don't think he should date anyone right now.
