I understand. I know I shouldn't have asked but I feel like if I completly ignore him he will think I don't care at all and see that this relationship isn't worth it. If I were in his shoes I would be upset if 2 weeks went by and he never asked me how I was when I looked upset? Maybe I am completly off base here.
Trust me, he knows how you feel about it. I'm guessing you've told him -- and shown him -- repeatedly before these past couple of weeks, correct?
You can also mix in some loving gestures -- AOSs (Acts of Service) -- but not to many, maybe 1x or 2x/week. Fold a pile of his laundry. Put the garbage out for him if that's a chore he normally does and hates having to do it (just thinking off the top of my head here, for female equivalents. For my wife, I would cover her up with a blanket if she fell asleep on the couch, giving her a kiss on the forehead; or maybe pull her car in the garage for her late at night when it was dark and creepy outside).
You will "know if it is working" in TIME -- weeks and months -- and you will measure it by what he DOES (or doesn't do), and not by what he SAYS.
