SP,
I have a SIL who it would appear has AOS for her love language. She is forever doing, doing for other people. It took me a long time to realize that she does this not because it's how she shows her love but because she wants the WOA. (have I used enough acronyms yet, LOL, oops there was another one)
She through and through craves kind words and people to sympathize with her. When you talk to her, she is likely to start out with what a horrible week she had so that the other person says, Oh my you poor thing..you do so much!

Watch your H closely and see if it is the kind words that he responds to, more than the AOS. And, you know what I've found? Whatever it is that we, thru our own description, have been lax in doing to or for our mates, is usually the one thing they need the most. It would be funny if it weren't so widespread and with often tragic consequences.

Anyway, try some WOA and see how he responds to that. Let us know!
