I asked a Virgo about his feelings and he turned cold?

He's a Virgo sun/Leo moon/Libra venus/Cancer Mars/Cancer Rising.

We've been dating for almost a year, but he won't commit. He's not dating other people, but he treats relationships like marriage. Sunday I was with him all day. We had an amazing time until the end when I asked about his feelings. He's affectionate and romantic, but he keeps all of his serious thoughts to himself. So I asked straight out how he felt about me while we were cuddling. The answer was terrible. All I got out of him was that I'm weird and moody, but I'm his future wife so he puts up with it, mixed with silence? I got mad, told him not to touch me, he backed off, took a trip to the store, and when he came back seeing I was still mad, he turned ice cold. He wouldn't look at me. He ignored everything I said or asked, and finally right before I left he stopped and took one long deep stare at me. Not one thing was said for the rest of the night. I didn't contact him and he didn't contact me until last night - asking what's up. I ended it quickly. Then this morning he asked me to come over and I said no. He always does this! He doesn't like talking things out (I do), so he ignores the problem, tries to skip over it when time has gone by, and acts oblivious to what he's done when I'm still angry. This same situation has happened twice before and at one point we stopped talking for over a month. He would contact me and I would still be mad until finally I just gave up and let it go. Why can't he just discuss it?
