Swagger, I'm so, so sorry to hear of these latest developments. It would probably be doable if you don't love her and don't care, but to be hurt like that, and to go through such drama when she doesn't come home, sound excruciating. To some degree I've been through that with my husband when he had his first affair. If it's any consolation, when the affair ended he was sorry and returned back to normal again (for a while). Can you do anything to find out what she's really up to? Can you drive past her mom's house at night and see if she's actually there when she says she is? Do you know anyone who might know her side of the story? Otherwise it seems you could try to leave for the next few weeks or just practice DB techniques to the utmost in hopes that things change in that time.
