how do cancers break up?

well i am not getting the best vibe from my cancer man at all. we talked last night and i cheered him up from a brutal mood he was in (just quit smoking two weeks ago and had to spend 1500 on getting his car fixed - his entire savings). after i talked to him i felt great, all week i've kind of been feeling like he's disconnecting from me (I have bitched about this in other posts and was able to come to terms with it, but right now it's driving me insane).

ever since he quit smoking things have been different. we see each other less, he txr's me less and i am the one initiating everything.

i'm wondering if he wants to end things but is too afraid to hurt me, or doesn't have the balls to say anything. how would a typical cancer end a relationship? i've been reading that you guys aren't likely to do things directly.
