He is obviously fantasising and experimenting - he's not sure what he's doing.
If you can, try to think about the need to give him time to work through his mess. It is 5 months - but that's not long in the scheme of things.
I'm desperate for some movement in a positive direction from my H at the moment, just like you.
And when I don't see any, I decide I will have to settle for closure - i.e. being done with what I should recognise as a hopeless situation.
BUT... then I remember that DB says don't lose hope.
Be more patient than you thought you could ever be.
Give your S TIME to work through his turmoil.
And understand that what they say and do today may not be what they say and do tomorrow.
And while you are still working on your self and with him, you still have the opportunity, at every interaction, to change the dynamic between you.
It may take a year, not 5 months; it may take 2 years.
Keep this sort of time frame in mind and then think about how you want to proceed. Would it be worth it if you had to wait longer for things to get better?
