My ex won't stop talking about how happy she is with her new man?

Okay, so I dated this girl from Ohio last year and we'll call her "X". In short, we didn't last more than 3 months before she gave me the "let's just be friends" talk. I admit, we really didn't have much of a connection. After that, there was a period where we were both single and occasionally I would text her trying to figure out if I still wanted to be friends with her. Well, after I jumped to conclusions that she was attracted to a good friend of mine (I know, I'm a complete idiot), I decided to unfriend her on facebook and completely shut her out of my life. That was last year, and she has found someone new in the distant state of Ohio (of course). I am no longer attracted to her in any way, shape or form. I've spent months moving on, and I'll be dating someone soon (If I play my cards right with this really wonderful woman I've met recently). The problem is, X won't stop telling me how happy she is with her new toy both in person and in an unwanted text message. I can't take it anymore. I've spent all this time trying to forget her and move on, but she refuses to let me with her constant talk of how wonderful this dude is. I don't do this to her. What's going on? How can I get on with my life if she has to keep bringing him up?
