Hey, Go easy on yourself. Detaching is a hard thing to do. After all, you didn't get married so you could be "detached" from your husband, none of us did!
At least he is continuing with the texting and it seems like you see each other pretty much every day. I know it sucks that things aren't where you want them to be. I have read posts on this board from people who haven't seen their H's in weeks or even months. So as long as you have frequent contact and he initiates some of the text-flirting and things like that, keep up the good work. But yeah, detaching is probably a good move. If I could just follow my own advice...hee hee
What activity are you looking into? If you want physical maybe you could join a dodgeball team, or roller derby...
