umm, I wouldn't take the shirt as sure sign that he's into a PA, there are other ways that could've happen, uh, he coudl've been giving himself a hand job, why would he had semen on him[/i ]if he were being intimate w/someone else? I wouldn't bring it up if I were you.
It is easy to read a WHOLE lot more into little things when dealing w/a supposed A (I acted like a fool 2x this month about something I thought had to do w/the ow when it turned out to be harmless, so this is experience talking.)
It took my H about 7mths to see that indeed, the grass wasnt' greener on the other side, lots of times separation do make a S see reality... other times it pushes them farther into the mess, so far that at some point they are either unwilling or unable to come back, I see it on so many situations on this board. So it is a win-lose situation if you ask him to leave, it isnt' guaranted that he'll see the light.
It is truly sad when the kids witness fights, I know as much as I tried not to have my son overhear he's listened to one to many fights and he also asked me "mom, why do you and dad fight so much?" I did appologize to him and told him that his dad I had some misunderstandings, that's all he needed to know. You dont' need to go into detail, kids dont' need this kind of responsibility right now, their whole world is based on us, so they dont' know to know the gruesome details of why daddy is acting like a jerk.
I'm guessing you'd use this "punishment" often, bringing your dd to bed, so she is really used to it. Be firm and dont' allow it anymore, it really is detrimental to your M to kick your H out of the bed. Go to the library and check out the books I suggested, I coudnt' afford books either, so I'd take kids there and while they'd play on the computer or did puzzles I'd check out their R books.
