There are things you should expect in this and the dreaded OW is one of the hardest to accept.
"Oh that won't happen to me." You do this to yourself you are going to be crushed.
"He won't lie to me." He will.
You did AMAZINGLY well, you did better than many of us 'old vets' would have done.
You enjoyed the day, and then were later hurt...that was yesterday. You get through this one day at a time.
The absolute hardest part about all of this (for me) was NOT getting my hopes up / expectations after a nice meeting. It was NOT talking about 'us' when she seemed in a good mood. You see the baby steps toward you, and you start thinking this is the 'turn around' point, and they will start running toward you...
They don't. Enjoy the small moments that are good, but pin no hopes on them...except that they might continue.
OK?
