<human>: I've been seeing this lovely guy for about a month. It's early days, but we get along incredibly well and have similar interests, lifestyles, and aspirations. 

The other day he wanted to have a conversation regarding where the relationship was going. He said that he was interested in pursuing an exclusive relationship, but that he wanted to disclose some information before we agreed to anything. It turns out that he has cheated on most of his previous partners. Usually the 'other women' have been strangers, though on occasion they have been with his friends, or his SO's friends at the time.

He said that the reason he was telling me was because he was actively trying to change his behaviour, and wanted to be honest about his past. Judging from the conversation, his motivations for cheating appear to stem from boredom. He did however state that the first couple of times, he did it just to 'see whether he could get her.'

So - now I find myself in a strange position. He hasn't given me any cause for concern up until this point. We get along well, and he's one of the few men that I have met that I feel as though I am compatible with in terms of personality. I respect that he is trying to work through his issues, and that he was upfront about his past. 

On the other hand, I also don't want to continue into a relationship where there is a higher likelihood that he will cheat. I believe that I get slightly jealous in relationships, and I don't know if the element of trust will remain over the long term. I may just end up second-guessing everything he says to me. Having said that, I also don't want to let my prejudice or the mere chance of cheating happening to prevent something really positive. 

At this point, I'm leaning towards breaking off the relationship. While I know that this may deter him from sharing his past with other future partners, I'm not sure that I am emotionally mature enough to handle this. Am I being an idiot?

Give me a shortened version of the text
<bot>: Great guy reveals that he is a serial cheater. Considering breaking off the relationship because I'm too scared to get my heart broken.
