Maybe he was just tired.

Just a thought but being a man & having his beautiful wife starting to show him some love & knowing he would not be able to finish off what is starting... well as I don't have a penis I probably cant answer that one.

Maybe you just caught him off guard also.

It is hard because I do love my partner & I have become use to limited physically contact from him. When I do get any it I am also a bit weary as sometimes the 5 mins of cuddles could lead to a day or so of crashing afterwards. So it's not that I don't want the contact I just don't enjoy seeing what it does to him the next day. Catch 22, I suppose.
