Can I get found??????HELP.............?

I already know what i did was wrong but i used someones fb pics to make a profile (not fb) and i got talking to this guy. I used a made up name and didn't give anything away about the persons identity, but they found the fb i was getting pics from and realized i was lying. i know that nothing i did was illegal, but im afraid that the person i was talking to is gonna us my ip addres from the pictures i sent in emails to find me. i know they can use that to find out what city i live in but can they use it to find out who i am? its embarring and stupid and i didnt do it for money or info or anything, just stupidity and crap. dont lecture me that what i did was wrong blah blah. i just want to know if this person can use my ip address to find out who i am even if what i did wasn't illegal.
