How did you know that you were being used as the babysitter. How did you know when she was out with OM?
My sitch is a little different - the OW lives out of town and I have no idea when she is in town.
We have a week on and week off schedule with kids. Maybe I should just let it stay with that schedule and not vary from it.
Was not always the OM, but was definitely as she was living 'single' and with no regard to what I had planned ... was like she expected me to be home regardless. Thats when I pulled the 180's and became non-availible even if I was ... fake it till ya make it.
If you have a schedule I would stick to it and pick your spots, trust your gut ... if its a place where you can demonstrate a change-180/PMA sure take the kids, but do not become the go-to babysitter they call when it suits them, at some point they need to realize what life will be like if the D happens .... this goes back to that fantasy talk, the image/life they have created in their brains without the LBS. One of my 180s was with my new job I could take S to his Dr visits, I have done almost all of these, showing I am a good father, hands on .. but not taking him all the time so she can party it up.
