Right now this advice doesn't mean much - but in your heart of hearts you know he isn't the right one if he can't support the highs and the lows. ATM it helps nothing, and you need to grieve what might be the loss of someone you love. Just remember you CAN get back up. I hope you can control the crash a little - I think you know it's coming, but if you are at all like me - knowing and stopping have nothing in common! Good luck to you and remember you have a support group here even if you just need to scream, cry or vent.
