Am I overthinking

My bf was gone for a few months. Normally when he comes back he is craving me and begging me for sex. This time is so different. He came back and has not asked me for sex once and he’s been back for a few days. I’ve had to ask for it. And when we got into an argument he threw it in my face he don’t be asking me for sex.

This is really getting to me and making me feel like he cheated. What do y’all think? I’m prob overthinking idk.
