Kakashi probably feels (and this is just a theory) that he cant get close to anyone because the minute that he does, that person is going to leave him. He probably idolized his dad...and he commits suicide. Finally becomes friends with Obito-- big rock crushes the kid. Forms a connection with his sensei and Rin-- large angry fox. If that doesnt psychologically scar a person, i dont know what will.

Oh, hell yes he has an abandonment complex! I mean, sheesh, who wouldn't? I bet a large part of the reason he was failing his students was to avoid getting close, which is part of why he reads all the time, imho.

Totally. Jiraiya totally wanted more than what Tsunade was willing to give. But, then again-- at times I dont think Tsunade realized how much she meant to Jiraiya.. More than a teammate.

*nods* I honestly think it's the latter, that she never realized how serious Jiraiya was about her, and I also think she was so burned out on having loved ones die that she just didn't want to go there again (subconciously).

I mean, for most of the manga I was loving the fact that Tsunade just keep turning him down, until I realized (at flashback to Naruto's parents, I think) how much Jiraiya actually loved her.
