I wish I could say that I haven't done all of this. The bottom line is - I have given backrubs, footrubs etc...all of which H likes and he says - "thank you". I have given bj's with no request for return (which he also loves) and I have had no oral from him since we were dating unless I directly ask. I have given kisses, shoulder pats, fanny pats - you name it. I occasionally get one back - sometimes I get what we call here the "wax on/wax off" from him if he doesn't want to be bothered. In short, I have touched him in myriad ways and had responses ranging from annoyed to mildly enthusiastic to very enthusiastic and all with no corresponding change in his behavior. I have done these things consistently throughout our relationship - over weeks, over months etc....
It is much the same with our "heart to heart" over the email - he hasn't changed his behavior a bit. My enthusiasm for trying is starting to abate. I'm 9 mos pregnant and I asked him to be a partner to me and he will do it only in the ways he chooses to while ignoring my needs.
He does show me that he loves me. And most of the time I actually believe he does. However, sometimes the credibility of his "love" for me gets a little strained by his lack of respect for the relationship currencies that I value the most.
