Of course there's no real timeline with MLC as each individual's crises is unique and as such, some need more time and some need less time to process. Some are "deeper in it" and some are almost transition like, where it's almost not really a crises, just confusion and change.
That said, as standard practice, MLC could take up to two years. It's the "classic" MLC aspect where they do a lot of the more outrageous stuff like partying all the time, young love interests, red, convertible sports car, etc, etc.
There are some MLCers who are borderline, so it's almost hard to tell there is anything going on, except for some confusion and more mild replay antics.
Suffice it to say, if your H is MLC and you feel he's in replay since May, it could be another year of replay and then a few years after that if he doesn't get "stuck".
I'm guessing you've read resources on MLC so you will know some or most of it.
The anger really begins in the second stage, just before replay. It will most likely last through most of the MLC, until they finally begin to come out of the so called tunnel.
How does one find the strength to go on? Many are surprised how much strength they actually DO have to survive this. You have more than you think you have. And detaching will be a primary skill you should learn as quickly as possible.
You will have to dig deep and realize that his anger is actually self directed, but it comes out as directed at you. If not you, it will be at someone or something else. That's where detachment will save you. Because you stop being a target for them as you stop reacting to their negative behaviours. They are angry with themselves over any number of things and in their MLC minds, their self protection mechanism causes them to think that everything that is wrong in their life is due to someone or something else, other than something going on inside of them.
Keep GALing. And also, take this time to work on yourself. Think about some of the stuff that your H may have complained about in you, prior to his MLC. Ask yourself if any of that stuff might be valid. If so, work on getting better at that stuff. Also, if there is anything that you feel personally, that you would like to improve in yourself, take the time now to work on those things. This will help keep your mind occupied and help you detach emotionally from his current words or actions and any expectations that you may have.
I don't envy anyone in a failing M, yet I think that someone who has a WAS at least has the opportunity to dig deep and realize that they had a hand in the failing M and work on those things and hopefully save their M, based on their own, positive, personal growth.
For an LBS with a MLC spouse, this is not the case. All the LBS can do is grow in positive ways and keep the road home paved and smooth and... if the LBS has not moved on by the time the MLC is over, perhaps the M will be saved.
