I definitely think I can come across as too strong for some girls, but that's usually because I'm really nervous and I don't feel like I'm cool enough for them in the first place.  In this current situation, it was very lax -- she called me up first and was the one who wanted to watch a movie.  I think I handled it normally.  I think with this girl, she really just wanted to be friends from the getgo.  Which is totally fine, just got mixed signals I think.
Also, I definitely do not come off as a creep IRL, thinking about it.  I don't say or do anything that's creepy.
I definitely can be eager though.  That's been a problem for a long time that I've tried to get better at.
