What does it mean when a guy says he has lost all respect for a girl?

so there's this guy who said he really liked me 2 years ago and I found myself developing feelings for him and told him. one day me and my friend decided we would add him on MSN with a different email and talk to him and went on cam with wigs on (didn't work because he realized it was me) and was just being silly, nothing sexual though. I know it was probably stupid and childish of us to do so and I've learned my lesson now but it was meant to be a bit of fun, he didn't like it at all and he told me I pissed him off. I told him I was sorry and it wasn't meant to hurt him. but he didn't seem to want to forgive me and told me he lost all respect for me. my friends say he overreacted but I felt and still feel bad about it.

1. do you think he overreacted?

2. what does it mean when a guy says to a girl he likes that he has lost all respect for her?

3. has he actually lost respect for me because ever since that happened we gradually started talking again and he is still sweet but not as much as before, pays compliments, says it sucks that he can't stop thinking about me, but I noticed he doesn't initiate contact first as much and sometimes he ignores my texts, whereas before he would never do that and he was really sweet. do you think he still respects me?

if you could help me out guys that would be great, thank you!
