So is He into me or Not? Shy Male Friend/Coworker being hot then cold?

Anonymous
Went out for a second time with a shy male coworker for drinks 6 days ago, We were flirting back and forth, holding hands in the bar, Linked arms while walking home, He cuddled up with me while walking because i Was cold. When hugging me goodbye he kissed my head, texted me afterwards saying he had an amazing time and next time we should just go over to his, Complimented me loads.

Since then he's barely replied to my texts, lets conversations taper out with shortish answers, Has left my last text on read for the past 3 days?

Am I reading too much into this? Was he even into me in the first place or am I being paranoid about this? I haven't seen him face to face in 5 days and he normally does do better with face to face conversation as he is a notoriously bad texter amongst my friends.
