It's hard not to feel like a tennis ball being batted around the court. Remember what I said: if you're feeling crazy, then it's because something crazy is going on.

Also something else to keep in mind is that his problems are not your problems. What ever crisis he is going through, although it clearly affects you and your life--and I'm not suggesting you minimize it-- remember his problem is not your problem. Picture it this way: if the two of you are in a rowboat and he falls in the water and is thrashing around, HE is in the water, not you. You don't help him if you also fall in and drown. You stay in the boat and throw him a line or something... but I suggest you detach somewhat and tell yourself, This is about something that is happening with him; it is not specifically about me.

I know you're going to say, But it IS about me, it affects me intimately, he has completely turned my life upside down.

But I'll repeat: think of the boat... he has fallen overboard and you do neither one of you any good if you jump in, too.

He's talking about going down the road not traveled... does he only talk about doing this sexually, or is he talking about quitting his job, moving, cashing in the 401K and buying a red Miata?

What precipitated this change... you said he had the leg injury, but he has recovered. Are there any other medical issues? Perhaps something he's not telling you about?

It's interesting that he proposes drastic changes in your patterns (i.e. admitting another man into your bed), but balks at you having a beer without him.

Something does not compute!
