Ex reached out to me only for sex

I feel pretty sad. I really was thinking of him and our relationship so innocently even if it wasn't the best at times but the other night at like 2am he was begging to see me and when i told him I don't feel comfortable seeing him at 2am because it feels like he just wants to have sex with me, he started lying saying he wanted to just hangout with me and go out to eat. When i suggested how about we go out to eat during the day he just kept insisting on see me right then. He agreed to see me next week during the day but since that night he hasn't texted me or called me. I feel so used, I didn't see him or have sex with him but is that all i mean to him now that im not his girlfriend anymore? I feel so sad, I don't even know him anymore.
