<human>: Can you provide a brief rundown of the text in within 3 sentences?

Been texting with this guy [26M] I [26F] met online for almost 2 months now. We would text pretty much all day every day. Went on two "dates" that I thought went well. There were no signs pointing toward disinterest, so I'm confused. He has been MIA/unresponsive for a week and a half now. (note- we have both been busy with finals and traveling home for the holidays). He's apologized in the past for being "quiet" on days he was super busy (I didn't really think anything of it), so I don't understand the sudden and continuing silence.

I have a history of being on the receiving end of the "slow fade," so I just assume this is moving in a similar direction. 

Why the dramatic shift? How long should I give it before concluding he's lost interest?

Any advice, besides that I need to stop overanalyzing?
