Eric, you are doing great, you've made such a progress...so good to see
About you questions... My H used to compliment me while having the affair. I would just say "thank you". And I do compliment him, when he does anything nice I acknowledge it or about the way he looks...I would say "That jacket looks really good on you" or "I like you in those jeans". Nothing sexual...just nice comments. I don't think there is harm in that. I always received positive reactions from H on my compliments.
And about being nice to each other while you know that she is seeing OM. Yeah, I was questioning that as well when I was in that position, but trust me she knows that you don't approve and that what she is doing is hurting you.
My H when he wanted to R said..."The love you were showing me throughout all of this is what made me want to come back".
So keep at it, you are on the right track
