Honestly I think you are crossing over into officially being friend zoned. And what [censored] is that you are communicating to your your H (whether you know it or not) that you approve of being friend zoned and you are ok with being cheated on because you continue to try to nice him back, like Steve said. Now you are making phone calls for him, that he could be doing himself?
A strong attractive woman would tell him to go fly a kite (I realize you might not feel strong, but you have to act "as if" just like it says in Divorce Busting.)
I hate to say it but, every one of these interactions lessens your H's attraction for you as a wife. If you continue what you're doing, I honestly don't see any hope for you at all in regards to reconciliation. Just my .02
