She sounds like an insecure woman who needs constant validation (fake hair, boobs, etc. multiple men). Don't let them get to you like that. I know it's easier said than done. Trust me. What you need to understand is that the opposite of love isn't hate; it's indifference. By still being angry, you are still caring in a sense which goes completely against you not giving a "frogs fat butt" about her. Stay strong. Stay positive.
I broke up with a guy about 15 months ago after being with him for almost 2 years and he was somewhat of a commitment phobe. Told me he was in NO way ready to get married. Lo and behold 1 year after our break up I found out he was engaged and guess what? I felt not a SINGLE thing towards the news. No anger. No sadness. Nada. That's how I knew I was fully over him
