My boyfriend is slipping away from me - what should I do?

Loulou1987
My boyfriend and I have only been dating for a few months but things became serious quite quickly and for the majority of our time together he has text me constantly every day, told me how much he hates the fact that he can only see me a couple of times a week (we live a train ride away from each other and both work full time), told me how happy I make him and how much he loves spending time with me and hates our time apart. He has always seemed very sincere about his feelings and has bought me little presents, made me cd's etc. Recently we had one bad weekend together (I was in a foul mood and probably behaving like a bit of a brat, which he didn't react to very well). Very suddenly he has cooled off despite my apologising for it and the fact that it is the only time we have every had a bad day together. I put it down to being a minor blip and didn't give it a second thought but he has suddenly cooled off stopped texting and calling me and hasn't asked to see me again. I said do you want us to stop seeing each other and he said he didn't want that, but he won't see me and has actually changed his facebook status so that his relationship status is hidden from public view. I've given him his space and tried to back off a bit but I just feel so shut out and confused, because in my mind all couples have bad days now and then and I didn't think it warranted such a dramatic change in behavior? I'm not being naive, I know for a fact that he genuinely really liked/likes me, I just don't know how to react to this and whether I should back off even more, tell him we should go on a break and see if that shocks him into action or push for an explanation? Please help.
