<human>: We've been together for a year and a few months, and maybe a month and a half ago I asked that we be in an open relationship. I was having a lot of trouble being in a committed relationship for so long at so young an age, but he didn't seem to really want to be open, but he also didn't mind it. At least that's what he told me. Last night I hooked up with another guy and my boyfriend came to my room presumably to go to bed. He didn't actually come in and see (he knocked on the door and I answered and asked him to come back in a little). But he seemed to be very upset, so I immediately went and put my clothes back on and tried to go find him (I also called and texted). I've texted him a few times today and Facebook messaged him and he hasn't answered. It's very obvious he's ignoring me, and I'm sure that it's because he's hurt/upset. He's very emotional and sweet and kind. I don't know what to do! I didn't do anything wrong, but I don't know what to do about the fact that he's completely ignoring me and refuses to talk to me. What do I say to him? What is he thinking? I just don't understand and it's causing me a lot of stress.

Provide a brief overview of the text.
<bot>: Boyfriend is seemingly upset that I hooked up with another guy even though we are in an open relationship. What do I do!? What is he thinking?!
