What is difference between

Hi everybody
What is difference between these sentence:
1:I think he was too embarrassed to ask me out, although he’s not a shy person.

2:I thought he was too embarrassed to ask me out, although he’s not a shy person.

What is the difference…

Just the usual tense difference:

I think - this is what you are thinking right now.
I thought - this is what you were thinking at an earlier time.

Thank you
