Hi Vicky, I just wanted to say welcome to our board. There are wonderful people here, who are very knowledgeable. Unfortunately, when it comes to marital problems there is no "one size fits all" but we will listen and try to help.
Perhaps, if your H brings "OM" up again, you can say something like, "I've decided right now, I need to take care of myself. I need to figure things out and not involve someone else." I agree with Puppy though, if he doesn't bring it up, let it alone and not mention "OM" again.
