Twitter - Ex Dilemma...?

[confusion818]

My ex-boyfriend and I were together for two years when we decided to go to college together. I already had my heart set on a school in the city, but after months of him begging me, I finally gave in and decided to go with him to the only college he got accepted to. Long Story short, he ended up cheating on me with this girl from our old high school, who always had a thing for him and was flirting with him constantly, broke up with me, and started a relationship with her just two days after he ended it with me. I was beyond heartbroken, hurt, angry (more emotions all bundled together than I’ve ever felt in my life). I chose the mature route and didn’t say a word about anything to either of them. I let them live their lives and be happy together (and believe me that took a lot of effort to be the bigger person in all of this)
Months later, I still feel the pain but choose to ignore it and live my life, making the best of whatever comes my way. Recently however, his current girlfriend aka the same one he left me for, is following me on Twitter and making rude comments on her page about anything I tweet or pictures I put up and stuff.
I have the overwhelming urge to say something to her. But I’m stuck because I don’t know if I should stay on the route I’ve been on and just ignore anything that has to do with them. Or if I should confront her.
I’m not going to be rude. Literally all I want to say is…”Please stop following me on Twitter. We are not friends so there is no reason for you to be in my business and keeping tabs on me, thank you.” And if she doesn’t stop following me, I’ll just block her.
So question is: Should I just block her? Or Should I get involved with conversation, asking her to stop following me (which, if argument occurs, could possibly help me vent some lingering anger out) and see how it goes from there?
Any advice is appreciated. Nothing mean please; I realize now that my decision to go to college for someone else was stupid. You live and you learn, I’m paying for that decision now.

Sorry this was so long.

And by the way.........yes, I am ten times more beautiful and intelligent than she is. I hear "Holy shit, that is what he left you for?!" always and it makes me chuckle everytime.

Yes this is long lol but I read it anyway... Give yourself some time and let everything with twitter blow over. She'll probably stop if you don't show any signs of it bothering you

Good for you being the bigger person in all of this, that takes a lot! I'd say just block her! You've gone this far ignoring her, keep up the good work
