Just like other things in life, standing is not for everyone. Some LBS have no desire to outlast their spouse's MLC.
Most here come to realize that DBing isn't about saving the marriage, it's about saving yourself. You've done that and are continuing to do that, so you are a success. If your H decided to return and you let him, it would have been a by product of the work you've already done.
You don't have to worry what anyone else thinks, only what's right for you and the children.
I'm going to venture to say that no one on this board will judge you or try to change your mind. It's your decision.
I'm sure you've thought this through and come to your decision with strength and clarity. When you're done, you're done.
