So this goes back to when I was a child, I had a friend who I lived on the same street as, I was very close with him untill I moved as a teenager, we lost contact and didn't speak untill we were about 18 and he contacted me. We got back in touch, he was going a university not far from me so we became friends again. A couple years later I start seeing someone and I introduce him to my friend. They get on great and end up practically becoming best friends. Fast foward about 9 years, We have 2 DC together and we're married, he was even the best man at our wedding. However we ended getting a divorce and it's been over a year since then, ex is in a new relationship. I've found myself becoming much closer to this friend lately, I thought I was imagining this at first but after a while we spoke about it and we've both noticed something going on between us. We just don't know whether to take it further or not, it may effect his friendship with my XH and complicate things (even more). I suppose it's not as if XH had introduced us, we've known eachother our entire lives but that doesn't change how close they are and us knowing eachother for so long just makes it even riskier if it were not to work out. I've only really listed the negatives and from not it looks like this would be a terrible idea. Then again XH might be fine with it, things may not be as awkward as I initially thought and it may work out. It's just deciding whether to take the risk or not
