8, I think there are two ways to look at this (and probably a lot more!), the first being that you show your love in the way that you feel comfortable and accept that you may get no response, so you live with it. Second, you look at the effect of your cards and flowers or whatever else and ask "is this helping the sitch?" if it is, do more and if it isn't then do something different. I always felt that as long as my W was not having adverse reactions to it or asking me to stop then I would continue in the way I believed a loving H should, but what do I know, I'm still spinning my wheels in my sitch!
