You go, girl! Have fun, as much as one can in these circumstances.
I don't know your complete sitch, but I just wanted to cheer you on in your GAL pursuits. Life is too short to be moping around, crying all day. (I need to learn this lesson too.)
I cannot imagine that your H can expect you to trust him soon after an affair. A year, maybe, if he's made some changes too. So, he probably wasn't ready to come back into the M, and nor were you to have him there. (Am I reading this right?) Initiating anything right now will seem like pursuit ... give him space to work on his own issues. You can't fix him, only he can.
