<human>: Condense the text into a few key points

So I have been seeing this guy for 3 weeks, we hung out a lot (5-6 times at least), slept together, he was being all sweet and nice then suddenly he stopped contacting me since Monday. 

I figured he lost interest/seeing someone else, so I stopped contacting him too since Wednesday.

Is it too soon to assume that he lost interest in me or should I just abandon the ship and delete him from everything?

Should I wait at least a week? Or should I quit now? Should I talk to him about it? Not sure what to do.

I'm not gonna contact him at all for now, I'm doing my own thing and trying to meet many friends as possible, and focusing on study.
<bot>: Guy suddenly stopped contacting me since Monday, should I wait little bit more for him to contact me, or should I delete every social contacts? Thanks!!!
