"Dating someone with mixed signals"

I've been seeing him for a month, but he disappears for days and gives me mixed signals. He's sweet and attentive, but it feels like he's playing games with me. I've been hurt before and I'm getting confused and hurt. I've had to tell him about my cancer and scars, but he's been weird about it. We've had some amazing nights, but it feels like he's not committed to anything. I've suggested meeting up, but he's always canceling or giving me mixed signals. I feel like I'm in the way and that he's not interested in a real relationship. I've had to warm up to intimacy, but he's been incredible in bed. I feel like I'm being played and I don't know what to do.
