MLc takes a lot of forms, and some of his behaviour is typical. I also think that some is not, but that is arguable.
What is less typical is that the majority of people here set, or are in the process of setting, firm boundaries, and displaying a realism about their situation. They might be waiting it out - and that is a personal decision, but they are not deluding themselves about what is going on. Which with all due respect, I think you are. For you MLC seems to be a licence for your h to treat you badly and for you to accept it.
it isn't a licence to behave badly it is a plausible explanation of why they might be doing this stuff,, and knowing the explanation, some decide to wait it out. Boundaries are essential for you. For the other parts of your life too. Please re and re-read 25years' posts, rather than arguing with them.
Apologies for the 2 x 4. but you are just not getting this imho. And you really need to for your sake.
