Should I feel bad for being annoyed that my grandmother comments on every Facebook status I post?

So I'm eighteen and I rarely see my grandmother because she lives in California and I live in Texas. I post Facebook statuses about once every other day, and I can't remember the last time I posted one she didn't comment on. It's like she thinks that I'm talking to her and she has to respond. I know she's just trying to connect with me, which is why I feel kinda bad for being seriously annoyed that she connects on every status I post, with questions and such (for example, I'll say, "anyone around me wanna go see a movie this weekend?" And she'll reply, "what movie?" And then proceed to carry out a long conversation (mostly one-way). I guess I hold a little bit of resentment for her because she abandoned my dad and two younger siblings when they were kids (ages thirteen, eight and five), and since I have such strong maternal instincts, I find it very hard to genuinely respect her. I love her, don't get me wrong, but I prefer to keep my maintain my once a year, two hour-long visit with her. She's also been very disrespectful towards my parents and their decisions in raising my brother and I, which also makes it hard for me to respect her. She's the kind of person who you can say, "I've got terminal cancer and I'm about to die, please come see me" to, and she'll be like, "oh sorry, I'm actually really busy, do you think you could hold it off for two weeks?" Anyway. Honestly, I'm really temped to just block her from seeing my statuses. Is that wrong of me?
