There isn't a hard and fast 'schedule' - just some general time frames that you can usually align as you look back. For MLC, 6-7 months is very, very early. Probably lots of Replay, the infatuation with the OP, and the kind of Monster antics you're talking about where you are still blamed for most things.
All you can really do is turn the attention toward yourself, securing your finances, and deciding the best course of action. There is a lot of unhealthy stuff here to heal from, and this can be a real opportunity for you to check out of his drama and find yourself. We all learn that at BD, our marriages are over. That doesn't mean we won't get an opportunity for a new relationship with the same person, based on a solid foundation we've laid with our shared past, but the quicker we can accept that there really isn't a 'going back' at this point, the better chance we will have to reconcile all that has happened to us amidst this.
His choices are his - you are not responsible for them, nor for his happiness or lack thereof. No marriage is perfect, even though some of us thought we were pretty close. I can promise you that if you let it, this pain you feel now will subside, and you WILL feel healthier, more powerful, and more *yourself* sooner than you think. That doesn't mean he isn't the one for you at all - I truly don't know what the story's end will be for you. But I know that through acceptance, I have created a more stable life for myself that may ultimately be the lighthouse my true love is drawn to (whoever that true love is - but I'd like to think it's the man I married).
