Hi Anna, I'm sorry to hear this and I agree with mvgfwd. It sounds like it is time for you to take advantage of the initial free consultations offered by L's. This will help you determine what support should be forthcoming from your H in the event he chooses to leave.
As you say, it sounds as though you will need to make plans in terms of childcare and finances. You and he S is by no means a bad thing IMHO. He is 'out' of the M just now anyway, and probably sees you as 'standing between' him and the green grass of being with AP. Probably he needs to get tummyache from greengrass overload in order to see what he is losing. If you are also solidly moving forward, making your own plans and letting him be, that will be the best plan I think.
I wouldn't try and pursuade him to stay. But you can let him know that S isn't your choice, but you respect that if it is his. And then let him go.....it is still early days in your sitch and this is by no means the end of things...
Good luck Anna xx
