TL;DR. First serious relationship for both of us. We entered a rough patch when I was cramming for my medical school finals. She cheated a couple nights before my finals with a colleague from her pharmacy. She tried to make amends but I cant seem to care.

Thanks for the advice everyone. Several posts really hit home. Firstly, that she is being selfish by pushing to continue the relationship. Secondly, my feelings are justified even if my friends keep pushing for reconciliation. Thirdly that breaking up is the way to go. Fourthly that if I loved her I would be able to forgive. Those words and some introspection got me to understand that the ambivalence I am feeling towards her is because I dont love her anymore. The moment she cheated is the moment when all my love was replaced with disgust and I am just wasting both of ours time. I realised the only reason I hadnt broken up with her was because I was being meek/lazy/going for the path with least resistance. Well 2 days ago I decided to man up and do the deed.

I took the day off work. I called 3 mutual friends and they came to my apartment to pack her stuff up. I then called her over to visit me after work (she had a halfday). When she came over I explained to her why I was breaking up and that I am giving back her stuff and the gifts she bought and will reimburse her for the Antartica trip. I told her I dont love her anymore, all I feel is disgust and its been a few months, these feelings wont change and the relationship is dead. She wailed and cried and said she'd do better/give her another chance/ I am the only man for her/ we are supposed to get married/have kids etc/ dont throw our future away etc. Frankly all her emotions had no effect on me. I just couldnt give a single fuck which just confirmed my intuition was right. She started causing a scene so my mutual friends escorted her out. She took her stuff but left me her gifts and said she doesnt want my money. I told her to keep NC and lose my number + give me back my house keys. We parted and I thought that was that.

As I said her parents are crazy traditional Indians. My dad called me yesterday to tell me about the shenanigans my exgf's parents pulled. After I broke up exgf went to her parents house. Exgfs dad and 2 brothers then stormed into my parents house talking all sorts of trash about how I am a player/scumbag who ruined their daughter; how my family has no honour and I have to marry their daughter if we were decent people (lol). They also threatened to ruin our reputation in the Indian community if they dont. My dad told them that I broke up with her due to cheating not the other way around. My dad has proof and will tell the rest of the Indian community about their daughters whoring around if he hears anything negative about my family. They asked to see the proof so my dad showed them the emails exgf sent to me after her cheating which I had forwarded to my brother for his advice. Exgfs family apologised, asked us not to say anything and then left.

Today I got a couple of calls from mutual friends. Apparently exgfs parents are dragging exgf back to India and will probably get her arranged married. Some of my friends suggested I reconcile to save her from this. I told them to shut up and stop trying to influence my love-life. If they feel so bad about the situation then they should go marry her before she gets taken to India. if they cant respect my feelings then they should lose my number. Frankly I couldnt care less about some of these mutual friends. Ive made new friends at work so I dont care if I lose some old friends over this break up.

Emotionally these last 2 days have been fantastic. Ive been busy at work and loving every moment of it (even the crap parts when I had to do a rectal exam on some 60 year old guy). It feels a weight has been lifted off of me. Im going to focus on being single for the next year and just enjoy it. My parents are also glad I broke up. Apparently they hated ex-gf because she had no clue about her indian background (couldnt speak the language, didnt know our history etc). They've gotten off my back about marriage and said they wouldnt push for it for at least the next few years. Everything's coming up Milhouse. I just hope theres no more bollywood style shenanigans/drama from exgfs parents.

tl;dr: Broke up. Some drama happened but I feel much better. I hope exgf fixes her life up but Im not going to be her knight in shining armour by marrying her to stop her getting arrange married in India.

edit: thanks again for the advice. hopefully i wont be using this account ever again.
