I agree, that would drive me insane too! I have a couple of neighbours who are like your hubby, and just a few moments of them talking 'at' me, switching subjects and going of on tangents leaves my brain aching trying to keep up, and me backing away to scuttle back into the safety of my home!!

Has your husband always been like this? I guess he may be anxious, like Leed said, but he could just be one of those people who has to fill any silences. He does need to know what he does tho, and be able to take a hint with good humour and give you a rest when you need it.

Have you sat down and talked with him (ha ha, sounds funny when talking about talking too much!) and tried to come to some agreement? I think waiting until you snap isnt a good way to handle it, and perhaps a few conversations, gently putting your point over may help?

Good luck, and hope you get to enjoy your weekends soon..
Hugs
