<human>: The story: (sorry it's long...)
When I was 14 my mom suddenly decided she really hated my dad and wanted to get a divorce. It was a very messy year that included lots of fighting, gossip, religion (seriously), and just general confusion as to why this was even happening.
Fast forward through all the crap of my dad begging my mom to stay, and then basically pushing my brother and I to try to maintain a relationship with my mom (which really did not work out at all, it was all too overwhelming so we gave up)... I'm 26 now, and I get a phone call that my mom will be in town and wants to meet up with my brother and I.

We saw her last year when we were visiting relatives in their home country. (My family is Taiwanese, if you're curious).
Chinese people are pretty hush-hush about divorces... its not abnormal for two people who are not in love to get married and have kids in their culture... but apparently my mom decided to take it to another level and make sure that our lives would not progress in a normal manner...

Anyway, I am basically developing ulcers and not able to focus at all at work because of the stress.
I spoke to my dad about it, and after his initial shock he said that I should do what I want, but ultimately speaking I still feel this overwhelming burden that I should reconcile with her. Even though all I actually want to do is run away. In fact, I want to tell her that I don't want her to contact me ever again. But this makes me feel like a really shitty person.

Also, pretty sure she is here in town because I'm basically close to getting married and she wants to be a part of that now =/

Any advice?

Can you give me the gist of the text in a nutshell?
<bot>: My mom left our family when I was 14, and wants to be a part of my life 12 years later after a very messy Divorce. Any tips on dealing with it?
