Maybe we need to define it, was it just a small kiss (x) or a big kiss (X)?
(sorry, Jo, Andy is giving me a giggle today)

Could it have just been a slip, otherwise maybe he is being overly nice in regards to the bday party. Or I suppose he could be drunk.

Either way, take care of yourself. I think it is hardest when they are overly nice. I never know what to expect next when my ex is nice and not sure whether to trust him.
