I think he is temperature checking. The truth is, if a walkaway wants you back they are going to walk through coals to do so. They will make it happen.
Piecing would never work unless they did.
I find that they also want what they cant have. So if you tell him "i only want to meet with you if you are ready to talk about reconciling with me and our relationship", you are telling him that you are right there waiting for him. Dont do that. Keep your value high.
If you do meet him, you need to keep it casual. No relationship talk. Jus logistics. Act as if. You have a lot of great things going for you. Remember that... its his loss. And hes the one that will lose out on the long run. Not you.
Please read marving's post in mlc. Its happening. Eyetie was an old poster here who had cancer and his wife left. As soon as he healed and moved on and truly got a life, she wanted him back. (He no longer wanted her though) read bluwave also. It wasnt until she moved on and gave up that he wanted her back.
Their affairs need time to fizzle out. Amd you need time to grieve and really examine your relationship.
I really think that the way we hold on, is to avoid the grieving. But our marriages are dead. And you have to face it before reconciliation can begin. It puts you in a ppsition of strength.
