Let me be clear....
...he breaks his vows every single time he takes a drink. When one person breaks their vows the other person is no longer bound to them.
Also, and as many others said, he is not helpless. He can get out of the damn chair himself, or stay in it and get run over. Plus, wheelchairs roll (if you roll them).
Lastly, you did not put the chair in the middle of the freeway-- HE DID.
My opinion only.
Take what you want and leave the rest.

P.s. Time for an Alanon meeting.
P.p.s. Again with all due respect and my opinion only, marriage is a disease and divorce is the beginning of the cure. My wife and I have been divorced for years at this point, and our relationship is better than it's ever been. We are together now purely because we want to be, not because of a socio-political/religious concept designed to chain women to men. There was a plan to marry again down the way, but as the years go by we talk about it less and less. Plus, nobody can stop us from calling each other husband and wife. That's what we want to do so we do it. ****-off Society.
