feeling empty at work today

my partner and i havent been on the same page sexually for a while now. we have this routine where we go home from work tired, have dinner, watch tv, and go to bed. its all so predictable and boring. last night though i finally snapped and asked him if hes still into me and sex or what? he said he loves me but just needs time. i dont think im ready for no but the doubt is killing me. on my lunch break today i found myself fantasizing about some stranger in a bar or something, wondering how it would feel to be wanted by someone else. its like all the passion we used to have is gone and id do anything to get it back.
