Is he unattracted to me? Please help!?

My fiancee and I always have - sometimes up to 3 times a day. The past few days we haven't. At all. I know he's been very stressed with work and tired- but last night I tried to wake him up with a BJ, and he didn't wake or even get an !! This morning he didn't come in to kiss me goodbye when he left for work. I don't know what's going on and I'm starting to feel unattractive and unloved. Could it be emotional for him or is he becoming disinterested in me? Please no rudeness in answers...thank you.
