No 2x4 needed. You're human and you demonstrated that. IMO a 2x4 is for someone who keeps getting the same advice over and over, keeps ignoring it and doing the same destructive things, then keeps posting on the board like they never got the advice in the first place and wonder why they keep getting the same bad reactions!
Your H's unexpected kiss is one of the peaks on the roller coaster. Know that tonight he may be cold and withdrawn. Often the WAS will "try on" being nice or affectionate to see how it feels. Then, they will fear you will interpret their actions to mean that everything is going to be OK and they'll retreat again. Expect this and don't let it bother you. Many folks on this board have lived through lots of hot and cold. It's part of the journey.
