Maybe post in the my readings forum? though what do I know, I'm a newbie here and keepin getting it wrong hehe
Strength: is it possible that you still have feelings for him more than he still has feelings for you? He could be sensing this and wanting you to be strong and independent, to move on from him so the two of you can be friends.
Alt/ he wants a friends with benefits sitch? - strength indicating an independent woman in dominance of her own sexual life (maybe he wants you to make the first move in that direction)
The Star: could mean he wants you to have hope of the right guy coming along and not pin all your romantic hopes on him.
Alt/ the star can indicate sexual fantasies, since you're asking 'what he wants with me' he wants his way with you without the relationship - again I see the star as this ethereal solitary creature, the kind that shows up in your life for a little magic (aka sex) and then dissappears into the moonlight- a booty call.
The sun: he wants his desire for this set up - or atleast for the friendship set up to come to light, for you to realize and accept this- perhaps he somehow thinks you're hanging on for more/regression.
ten of cups: is often seen as the end all wish for relationship and marriage, but I also see it as just wanting an ideal situation (that is, the querents idea of an ideal situation) peace harmony - no relationship drama just the 'good stuff' as you said 'celebration' I think this dude wants to party with you still, if ya know what I mean ;-) (could also go back to friendship, wants to go out with you as friends)
My final word on Strength, though, I think either way he wants *something* with you, he also wants strong boundries to be set, something clear and decided (he's not enjoying the guess work of where you two stand with eachother) this is clarified by the sun.
I hope atleast some of this is helpful
