As for his love language, and acts of service, I'd keep it dim with *H*, but I WOULD then (if that's his LL) do acts of service for daughter. Maybe even with him. Show him how lavishly you enjoy serving those you love, but instead of directing it at him, do it for D, in front of him or with him. Make him want to be the one you love and serve.
I want to clarify...this is NOT to be done controlling/manipulative. This is only if AOS is his LL, and then it should be a 180...something you make a permanent change, for YOU to be a better person, and to let those you love feel the love you have for them. NOT a gimmick to try to win him back.
