Why do I always do this?

So Will and I are pretty much happy. Yeah, we're getting married so that makes sense right? Well, sometimes I still wonder why do I always stay ill at him? For example, tonight we watched an hour and a half stupid zombie show and after it was done I asked to watch something else. When Will didn't seem to interested, I kinda snapped at him that we always watch what he wants to watch. All along, I could have come to the bedroom and watched whatever I wanted to watch on the TV that is actually mine instead of asking him to watch something I wanted to watch on his TV.  Really stupid huh? I wish I didn't pick fights with him... but I always seem to. Sigh... Easier said than done.
