Sadly another cheating story ... found out my boyfriend of nearly 3 years on fabswingers, with positive recent reviews 
Of course he is going to get dumped. But we are off to holiday together with my DC (whom he's known for nearly 2 years) in 3 days for 9 days, a long drive abroad and accommodation booked and paid.
He doesn't know yet I know.
Do I carry on for holidays and dump him straight after?
Do I reveal and we still try and go on amicable terms?
Do I reveal and we cancel holiday? (It will be difficult to explain to DC who are looking forward)
What do I do?
