The Switch.....

My SO and I have been on and off for three years now and Just like every relationship there's hardships! Our hardships seem to keep us off more than we are on! I'm starting to think my partner is enjoying the fact that we aren't in a relationship but still are doing relationship type things like sex , cuddling, talking basically things you do when your fully committed... Help should I demand a relationship or leave! My hardships are time and trust he's are understanding and listening! Together ours is friendship but I continue to say let's not have sex to work this out and then he'll make me feel guilty by saying I'm having sex with someone else. I'm tired of this roller coaster
