Mad at husband

It's been a tough week with flu in the house.. apart from me.. so no itimacy.. nor did we want to.. come a chance when we can.. children are better.. in their own bed.. husband better.. he decides to go out.. to the club.. and not with his friend.. who's recently widowed but on his own.. yes he knows people out but even so.. he never seems in the mood.. i always initiate with odd times from him.. he doesn't watch porn.. he doesn't masterbate.. in fact i do because i need to.. not sure what to think but feel lonely in my marriage.. i told him all this and he promises me sex tomorrow.. i feel like a beggar but i at least want sex once a week.. now it's becoming once a fortnight with me being in a bad mood.. and feeling unwanted. Edit: he has a low sex drive.. even with his ex.
