Abstaining from sex.

I'm interested in abstaining until my fiance and I get married. The problem is we've been together two years and sexually active the entire time. I've reached a point in this relationship that I'm comfortable and he's comfortable and we spend more Times on our phones then actually talking. Don't get me wrong we have some good times still but it's just losing that desire that I crave and most of the fault honestly is living together. From money stress to work drama we have been in a crappy mood for months now. Adulting soccer punched us in the gut and our relationship suffered. I want us to get back to craving to know every detail of eachother and having desire filled makeout sessions for hours! love him so much I just dont know if I'm just like hey I dont want to have sex anymore for 6 months if that is fair. I don't want him to feel punished or unwanted or cause more harm to our relationship.

** spicing up the bedroom wouldn't really benefit our relationship we already have great sex and then we go back to our moods.

** "denying a man sex" I don't feel good about it afterwords. We use to lay in bed for hours afterwords talking and laughing now its more of a 'we used each others bodies' feeling.
