Besides the text messaging, which honestly I understand from his side of the situation, how are things at home? I mean you see eachother every day so he probably doesn't feel the need to text you or call you. My husband and I worked in the same building for 6 years but honestly, we hardly saw eachother during the day.
And in terms of his approval, I'm guessing you never got his disapproval throughout the years you've been together so getting his 'approval' would be something you already have?
I don't know, maybe you should talk to him if you don't feel he is being affectionate at home.
You can't out-exercise poor eating habits.
