hi audigger-
is your wife in AA now that she is out of rehab?
just because she is not drinking, does not mean that the behavior will change. when As stop drinking, they are still in what we call "the fog". it can take years of recovery work for her to have the fog lift.
two weeks is not a very long time. be alert! it would be good if you could get to alanon meeting for yourself.
if it was me, i wouldn't trust her. sex in the parking lot with more than one man and repeatedly is not a one-off drunken mistake.
i think it would be good if you read more here, attended alanon and also, took some immediate steps to protect yourself and your family. for example, do you have any shared bank accounts? credit cards? whose name are the cars in?
what if she falls off the wagon and crashes the car? what if she drains the bank accounts? are you leaving the child in her care?
in my mind, there are immediate, practical things which need to be addressed to protect your liability in regard to her actions. then, there is the beginning of recovery for yourself.
