Cancer and friend

I need advice on about a friend I've for over a year who has had interest in me for as long as I remember but at the time we were both taken but now that we're not and i show him interest it started off good spending alot of time together but after about a month of much time spent together he has gotten really distant I don't know if him being an Aquarius has anything to do with it, but from a cancer's perspective what do you think?

It depends on if U have had sex with him or not? If U have given yourself to him to easy or to earlier, Yes he will probably back off! I sense that Cancers R cautious they just R not THAT easy going right!
