slowly, i know it is a great thing that he feels safe to speak to you. you have created that intimacy between you. but remember, OW may always be a very touchy thing for you to deal with. and there are thousands of ways where you can share intimacy together.
if his speaking of his feelings about OW start to cause you to dissect his mind again, maybe you could avoid these conversations? maybe you can think of 3 or 4 other ways to share intamcay that would fill that hole if you cut out these conversations, then you will have even more intimacy then before. without any of the hurt and confusion a talk about OW may leave you with.
and you also mentioned that you want a little more work on your r from his end. hummm, is there any action you can take to get more of what you want? what happened in the past that made you feel like he was very into your r? what is different now? can you do more of the same to get that again? or can you ask him for more times to sit and discuss things?
what will he be doing if he is working on your r? talking more? buying flowers? spending more time with you? is there anything you can do right now to get a little more of that?
