Lantz, read what Mike said:
I don't think people are deliberately avoiding you in general, but your characters do share your tendancy to miscommunicate a lot, which makes the other characters wary of them ICly. For example the stuff with Sakura getting mad at Rin, where you completely misunderstood what Rin was saying and acting like she was claiming Toshi was worse than Gil. Similarly, Taiga was quite mean to Kiyoshi when they first met, and not every character is going to just overlook that.
If someone was a douche to you, would you want to go talk to them?
Taiga was really mean to Kiyoshi when they first met, and Sakura had this very superior attitude when she met the main group.
Look at the characters who get along well with people and have a lot of play. They don't have to be super nice to get interaction. Lancer won respect by being Lancer- He talked to people, got pissy at both Archers, and he's bro. Haku-chan gets people talking to her because she's nice and not really helpless, but sort of brings out protective instincts in people.
Not to mention, having interaction doesn't mean they have to be buddy buddy. Look at Forest and Rider's interaction. They're not going to go out and be best friends, but they did talk to each other. Even if Forest found Rider's constant perv a little scary and Rider didn't like the fact that Forest could see into her mind.
