I don't know, I feel like some of the texts you were getting may have been misread. It's difficult to interpret tone via text. It's hard NOT to read a text as standoffish or short or cold if you're feeling like the person is being that way to you already, you know? I think maybe these people were superficial friends, that they weren't in a place where they really wanted to worry about your feelings at all, so when they were put in a position of having to explain that, for example, not texting wasn't meant to leave you out, they just honestly forgot to text, they decided that they didn't want to be in that kind of position anymore. It's not your fault or their fault, they just aren't the type of friends that you need.
