Does it sound like my boyfriend wants to break up with me?

Here's the thing: we're in an LDR so we have to rely a lot on texting to keep our relationship going (but do see other on weekends usually). He usually texts me everyday, but lately he hasn't been doing that. Tuesday and Thursday he didn't text me, and on Wednesday and Friday he didn't text me until late at night (about an hour before my texting goes down for the night),. Again, this is really weird because I can usually rely on him to start the conversation everyday. Today I was continuing the conversation he had started the night before, asking him if he went to dnd. He said "Yeah it was run." This was strange too, I guess he meant "fun" when he said "run," but it's out of character for him to make typos like that. I texted him back, but so far he has not responded. Does it sound like he wants to break up with me?
