Best Friends

So tell me what you would you do if you were in my situation?

My best friend (#1), is recently married, we have been friends since high school, about 9 years total. When she came back from her honeymoon, she was totally happy with being married. it was always hubby this, hubby that...and then me and her started hanging out less, I understand that it happens.

A couple months later, happily ever after wasnt really working out ( go figure). I did my best to give her the best advice that I could. Sadly enough the only thing she would ever talk about is how she wanted her hubby cheat so that he would divorce her.

A couple of weeks later, she calls me saying that she was so happy, and she was in love. I was so happy for her, and also very happy to hear that her and the hubby were working things out...but that wasnt the case..

She had a boyfriend, someone that she had met through MY myspace, (wow)...right? Her new boyfriend also works for the same company I work for. I always wanted what was best for her, and I supported her. Even though I completely hated the idea that she was cheating. She always said that she just wanted a guy that would treat her right, and let her be herself...but the boyfriend wanted her to change her ways and she let him. The boyfriend, is vegan, doesnt smoke or drink or parties...

She changed so fast that I didnt even know who she was anymore. She stopped eating non-veg, stopped smoking ( in front of him) and stopped drinking. I thought that that this was good for her, but when a person tries to change someone that doesnt want to be changed, its all bad.

She lied to him ( the boyfriend) about everything, she did everything like usual but just behind his back. She thought that the point of her cheating was that she would get to do whatever she wanted to, I fail to understand some people.
