Just need to vent a little bit😯

Dated this guy for almost 3 years then he downgraded us to friends who still have sex. I'm so in love with him I know he's using me but if it means still having him as apart of my life I'll do anything even if it means sex every once in a while when he hits me up. I feel so low but I don't want to be alone entirely. I hope so bad that he'll love me again and take me back if I keep having sex with him 😳
