I agree with you both,. I would have been ok with the mother dying, Ted moving on, heck I might have even been ok with him ending up with Robin (though I would have probably rolled my eyes out of their sockets) if they had handled it better. The kids reaction did feel really skeevy. Yes, it's been six years since their mother died - but come on, it was their MOTHER. They just heard a long story about how their father was forever hung up on an ex-girlfriend and their response is "Oh cool - you obviously love Aunt Robin, go for it!" No, a thousand times, no.
