Hi OD, that sounds like a good idea. The DBers certainly seem to feel that boundaries may be helpful here. And only you know what you are comfortable is.
Reading your sitch, it certainly sounds to me as though your W is quite willing to openly date, and for you to know where she's going etc. My take is that she's checked out of the marriage, she has told you she's checked out - and so she feels this is perfectly okay.
On the other hand, you are here on this site, and wanting to save your M if it is possible - but she's just not a willing participant for that ATM. So, what do you do? I think it comes down to what you are willing to live with and tolerate. You have a choice of being in your home at weekends, and having the dating 'in your face' - or setting some boundaries which may mean it is less in your face - or choosing to live elsewhere at weekends - which may bring some respite from the dating, but has pros and cons.
I agree with the comment above. I wouldn't consider what your W may think of this. This decision is mainly one for you. Have you read no more mr nice guy? I don't know the content, but the title suggests it might be helpful right now....maybe others can chime in and verify that? Tx
