Should I be insulted or Flattered?

Miss

I found out my man regularly rereads my erotic story I sent him, he said nearly everyday he masturbates to it. However our sex life has dwindled down to once every three weeks.

I'll try to initiate, but I either get a refusal or am told to wait a few hours. If he initiates, I'm all for it. But he's going for my words written from the perspective of a character I created over the real me. I feel rejected, even if it's my previous thoughts that get him off.

Am I justified to feeling jealous over a fictional character I created, am I meant to feel insulted he is attracted to this fictional being more than me. or am I to feel flattered because it's still ultimately me getting him off even though I never know about it.

I play an inactive role to his sexual release now. Obviously I currently feel jealous and insulted. So if I'm wrong in feeling this way, I need to be told.
