Telling him about your mom's feelings - That doesn't seem too over the line. But I would maybe hold back on that stuff, any further.
I remember when we first started parting with no hug, no ILY. It hurt. How to make it stop hurting? Don't expect it! Change your mind! Be happy regardless! He'll notice that MORE.
My W's "explanation" for why she had an affair was that I was never happy. No, not SHE was never happy. Her observation was that I was never happy. So that was her "excuse" to go have an affair. Lately she has asked me, "Why are you so happy all the time?" Curious. (Her excuse has now changed to You neverseemedhappy.)
Why does she perceive me to be happy? Because I am making a conscious effort. I am finding joy in the things I do and I am doing the things that bring me joy. Even if what I had expected before is no longer available to me (ILY, or a simple kiss goodbye) I can still find joy and contentment in other things.
Give that gift to yourself.
