The guys a loser if he's not being truthfull to both of you or if he has one face for when your alone with him and another face when your around other people. If two people like having sex together but don't consider themselve to be together thats ok as long as they are truthful about it. But acting like we're in love when your alone and then "your that girl I use to know when he gets around other girls or friends" is the give away that HE can't face his own truth. If you want USE HIM FOR SEX but don't ell him thats what your doing as he'll realize your on to his style and he'll adjust with some other fake but seemedly deeper bullshit, about how shes got money and thats why he sleeps with her but he really loves you bla bla fuc*ing bla bla bla. Don't let him drag you down, but don't put negitive energy his way as it bounces back to you. Just kindly have sex with him at your likeing/conveniance if thats what you want to do. The give away here is how he acts infront of other people about you, not how he acts when your alone.
