Boyfriend wants "a couple days to clear his head" after argument. What should I expect?

Anonymous
My boyfriend and I had a huge fight last night. We were both out having drinks at the bar where he works and, after one too many drinks on both of our accounts, we ended up arguing in public. Basically, I'd been feeling like he takes me for granted and hadn't bothered discussing it with him. And it all came out in the wrong way and at the wrong time. I know that he's been overworked lately and that we've both been stressed about our current employment situations, on top of trying to plan for our upcoming relocation. Now he feels that I've embarrassed him in front of his friends and colleagues, a mistake I also made just a few short weeks into our 7-month relationship that almost brought it to an abrupt end.

What he didn't know - and what I later told him when we were fighting back at home - was that yesterday marked 10 years to the day since I was raped. I hadn't discussed this with my boyfriend before. In fact, I've hardly discussed it with anyone outside of my therapist and my family. When I told him, he became angry that I didn't come to him with it before - especially, he said, since he'd been so open with me about his abusive childhood. And I received no empathy whatsoever - just anger. What I fail to understand is how he can be angry at me for choosing not to tell him about what happened, when he obviously can't or won't respond accordingly.

We slept on opposite sides of the bed last night and, when I woke, I leaned over to tell him that I loved him and that I was sorry for my behavior. He told me that he loved me, but later said that he thought we should spend a couple days apart because he was "still angry" and because he "need[ed] time to think."

While I understand that I could have dealt with the issues at hand in a more constructive manner and at a more appropriate time, I do feel a bit unapologetic given his reaction to my revelation. As I told him, it's not something I particularly enjoy discussing or thinking about.

I also don't particularly like the idea of "time off." I understand that he may need time to cool down, but I'm a much bigger proponent of talking things out in the immediate aftermath as opposed to waiting and then pretending that the argument never happened in the first place.

Thoughts? Is he trying to end things or does he really just need some time with no contact to cool down and work things out?

UPDATE: He has text the past 2 nights to let me know he's gotten home safe. He says he "does love me" but that he needs more time. I asked him if we'd get thru this; he said he "hoped" and that he promised he'd try.
