cw, I'm sorry you have returned...but I don't think your h was truly baked up before he returned home. In my opinion, based on your first posting, I think your h is cake eating. He's got the best of both worlds and why should he be in any hurry to walk out the door? He's not sure what he wants to do and isn't ready to cut the cord that binds the two of you just yet. Maybe the ow isn't ready to commit to a full time live in. One can only guess at such things until more is revealed.
Yes, it's a bit different this time around because he's taking his time in plotting is course of action. I do hope that you've been checked out by a physician and are okay. You just never know what they pick up and bring home to the spouses, i.e., the gift that keeps on giving.
I'm glad to see that you've scheduled an IC appointment. The IC should be able to help you better understand how to put boundaries into place for you so that you can feel better about you and your situation.
Again, I'm very sorry you are here...but we'll help your sort through stuff and get back on track once again and help you to realize that you are the prize and a valuable person not only here, but in the real world. Keep the focus on you and your children and allow him to twirl in the wind.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
