<human>: Can you give me a shortened version of the text?

He [m23] told me a few weeks ago that he wants to get back together. Lets call him Jack.  Jack and I were together for 2 years. Lived together a year after we broke up (out of necessity) but we remained very close for this last year we have not lived together. We've always been nice to each other even after we broke up. I asked about a year ago if we could get back together, Jack said no. He told me to move on and pursue a relationship with a fella I've been talking to for awhile. Lets call him Frank. 

So....I get over Jack, that was very hard to do, and I pursue Frank. Jack and I still talk and hang out. He knows that Frank and I are starting get close. Frank is a very private person and because he let me into his life says a lot about our friendship. Frank and I are almost to the point that we need to have a chat of if we're going to move forward with a relationship or stay friends. 

Now Jack tells me that breaking up with me was the worst mistake of his life and we should be together forever, he'll change and put more effort into a relationship.  Jack is an atheist and I am a christian. This was a reoccurring fight. Im not willing to move my stance on this. Jack also says that I can only be in his life as a romantic partner, or not at all. 

What ever I choose, someone gets hurt. I just don't know if I'm being unfair to Jack by not giving him a second chance.  Its not like we broke up last week, it was 2 years ago. I think its because of the holidays and that Frank and I are getting close, that Jack is thinking about being with me. I want to be fair to both guys. 
Im open to advice or opinions.
<bot>: He wants to get back together after 2 years broken up. Mysteriously this happens at the same time another guy and I are starting to get close. Im so confused.
