Aw Deb, Try to hang in there. It sounds like he is just readjusting to his former way of life. You know, he has been living this double life for so long that it has become habit to him. I'm sure it will take a while to form a new habit and get used to life without the drama.
As far as the emails, I would write him first! Maybe find a funny e-card or something with some humor in it. I think the man needs a good laugh. And to remember that life DOES hold joy and happiness, even after you have screwed up so massively. If he sees that coming from you, he will be all the more drawn to you.
As far as confession goes, well, he probably does not feel that he SHOULD be forgiven just yet. Especially if he is maintaining contact with her, albeit much less than what he did. I, too, think that when he finally goes to conf you will know with full certainty that he is back!
Also can you imagine going into the confessional and saying that out loud?? Good grief, that would take some brass balls to accomplish that! I feel for him, but at the same time, it must be done. I will pray that he receives the strength to do it.
As far as the devil being present, I really do believe that is what's going on. I think that the devil works in very strange ways..such as the AC going out. Nothing that screams "devil!" but it is SUCH an inconvenience, causes stress and tension and crabbiness and could bring out feelings or words that otherwise would not have surfaced.
Also I found this website the other day that sends naughty e-cards. H would FREAK OUT if I ever sent him something like that, but maybe in time your H would enjoy something like that? They didn't look too over the top, just not "cutesy" like the love ones that are on bluemountain and sites like that.
Well, I'm off to check out the website you posted; looks interesting!
