Avoidance?

Do you ever get the feeling that someone is avoiding you and you can't figure out why? One of my favorite people hasn't really been talking to me lately, and when she is, it's superficial stuff. (How was your day. etc) I know she must be busy, but I can't get over the feeling that I've somehow offended her. Politics? Religion? Family?
I don't know. Maybe I'm just paranoid and she's just busy. Or maybe she just likes her new friends better. lol
Still, I can't help but be a little hurt. More than that, I'm worried that I hurt/offended HER in some way. That's the last thing I'd want to do.

Family

I'm so tired of some members of my family who never return a phone call, text or email unless they want something.
I'm thinking of one person in particular, who I used to be very close to, who is suddenly "so busy" that she never has time to talk or anything. I don't think she's NOT busy, but really? SOOOO busy that she can't find time to chat? (But can find time to go on dates, take naps, hang out with girlfriends, play on FB, go to bars, etc.) Wow - I feel loved.
