What if he just didn't want to sign because he didn't want to be a part of that / any? political issue? ... Didn't want the woman to know that's the reason, so he gave the woman a lame excuse as to why he didn't sign. Is he one to normaly involve himself in such issues, even if it is just on a ballot / petition level? I for one am uncomfortable with signing a petition unless I believe I know the true agenda behind it. Most of them make them sound like their's is for some noble cause until you seek the whole story.
Anyway I digress ... again the point I'm making is ... there's just as much a chance his decision not to sign may not remotely have anything to do with what his current address is or isn't.
... and Sue, I like the idea of talking your Pastor on what approach you may wish to take as to where H may stand now. She may be in a unique positon to give you appropriate guidance. At the very least, I'm sure she wouldn't mind being a sounding board so you can express your thoughts out loud just so you can hear what they really sound like. Sometimes we just needs some one to listen to what we need to say.
(((Sue))) I know how frustating it is when our S keeps their thoughts all bottled up and doesn't share them with us. In this regard, CAW is much like your H and I too, like you, am trying to remain patient in hopes that she will one day on her own see the value of wanting to open up and share her most private thoughts with me.
In the meantime, I still try to seek ways that may work at entice her to open up some. Some call them feelers. Sometimes they work ... sometimes they don't. State in a form of an observation, like, "I couldn't help but notice you seemed uncomfortable at church the other night when that petition was going around." He may just shrug his shoulders at you ... then let it go ... or he may decide to share with you what he was thinking about then.
P.S. The next time you start to "mind-read" why your H reacted a certain way, why not force yourself to list three positive instead? It seems to work for so many others here.
