<human>: Give me a shortened version of the text

I was with my ex for 3 years. We broke up about 2 months ago. We had been having a lot of issues (sexual incompatibility, financial disagreements, different goals in life, generally I had began to feel more of a platonic love for him..) and I chose to end it. He was devastated. 

His cousin lives in the same city as us, and I've always gotten on well with him and found him very attractive. I tried not to over analyze that when I was with my ex, but now I think about it more. I think his cousin may have felt similarly about me. I never talked to him about it obviously and we haven't seen each other in a few months, but a big part of me really wants to ask him out.

I will most likely never pursue anything with him, because I think it might always be wrong to do, but I'm still curious as to what others think. Is there a certain amount of time that might make it okay for anything to happen there? If my ex moved on, could it maybe be not horrible? Or is that always going to be unacceptable?
<bot>: I have a crush on my ex-boyfriend's cousin and would love to go out with him sometime, but I don't want to hurt anyone or be a horrible person. Should I just forget about it?
