FInding out who the number is can be pretty simple, call it from pay phones, have friends call it for you, etc.... Eventually you should be able to get a name from it somehow. Have you googled the number, sometimes you can find info that way if it is a business owner or something like that? As for dealing with the cake eating, that will be a very tough one to deal with, especially living in the same home. That will have to be a matter of you figuring out what does and does not work. As far as a PA, EA, does it really matter? In my opinion, a female having an EA is more dangerous to a relationship than a PA. May not hurt as much at the time, but it is definitely more destructive. A female needs love and emotion typically to have sex, it is a building block. Be very careful with that path if that is what is happening. Shock
