worth it? obviously, in HaShems plan, this marriage had to be, whether anyone understands or not. is His plan not worth it? not up to us to say whether or not its worth it. it is up to us to trust HaShem that it had to happen for a reason (ie: if they were married long enough and had kids, those kids obviously had to be born), and see what we could learn from the situation to come better.
by we i mean general population, as i am not yet married. and i give all those marrieds and singles a bracha never to have to go through something like this, and if someone here did, or is, we have no idea what pain you are going through, but may HaShem help you and guide you and always be there for you and soon give you a reason to rejoice like never before!
