Am a regular but changed name for this, will try and be brief; 3 years ago ex-boyf got in contact and we had an e-mail relationship. He eventually called an end to it because his wife found out.
All this time has gone by and I contacted him again out of curiosity, he has now replied, and neither of us have referred to the past or said how we feel, just niceties.
Should I ignore this and just forget about it now? Or cause myself a whole lot of truoble again?
