Low labido :(

Okay so I've been on depo the last 6 months and I have noticed I have a extremely low labido, I am recently married and I used to love sex but now I don't think about it at all, when my husband tries to get romantic I can't stand to be touched., sometimes I have to force myself to have sex. (When I say that I mean mentally I want to be able to please my husband but my body just doesn't get turned on) I have no idea what to do... I dont want him to end up looking somewhere else even though I know he's Not like that.. what can I do?
