20 years ago, I had a brief relationship with a lovely man that didn't work out and he ended it after about 4 months. I was upset but realised it was the right decision. We weren't sexually compatible although I didn't fully realise back then as I was only 18 and fairly inexperienced.
We stayed friends though and I became friends with his best mate. You've guessed it, there was a real spark with his best friend and we ended up in bed after a drunken night out.
However, unbeknownst to us, we had been spotted kissing in the bar by ex's flatmate who then told ex.
Well, the shit hit the fan and after a mahoosive row, ex and I never spoke to each other again.
Fast forward 20 years and I bumped into ex's best friend!!! And the spark was still there. We spent hours catching up (it turned out he and ex fell out badly at first but gradually sorted things out between them and were now close friends again) and talked about what could have been.
We've been seeing each other now for a couple of months and have been talking about what to say to ex. So far he doesn't know that we're back in touch let alone dating.
The question is, when to tell him. And how. The last thing I want is to come between two friends again like I did when I was young and foolish.
What's the best thing to do?
