My ex and me split up a month or so ago and I want her back but she wants to be single. All we do now is have sex. Everytime she is drunk she shows up at my house and we have sex. The sex is amazing, I always give her multiple orgasms. I know at this point that she is just using me for sex. Should I quit being so nice and lovey dovey? Should I just act like all I want is sex and treat her as such?
