I'm a senior in college right now home for the break. I act pretty cold to  my parents, not intentionally but I do acknowledge I don't talk to them like I do friends. I would feel  awkward going out to eat with them one on  one and I only rarely initiate  conversation with them. This is what they're upset about, that I don't actively want to / seek out to spend time with them or talk to them. That said, I do occasionally joke around with them and whatnot. 

&amp;#x200B;

My reasoning:

1. They actively judge me negatively on whatever I do. For example, I used to be extremely antisocial in high school and they consistently called me weird / judged me for not being social.
2. After developing a social life in college, they judged me for partying too much, so  I stopped talking about what I do in college, parties I go to, etc. with them. I came home buzzed a couple of days ago and they pretty much yelled at me. 
3. They were extremely non-supportive of my weight loss journey, I lost 90 lbs over two years and it seems all they focused on throughout the process was calling me anorexic for counting calories and watching what I eat.
4. They consistently and heatedly argued intensely in my youth which always added stress to my life as a kid, I feel I still slightly resent them for this, deep down. 
5. They migrated from a poor Asian country before I was born and always bring this up whenever we get into arguments, claiming they gave up their life back there so I could have a better life here. I have nothing to refute this and I am grateful but this is what they bring up to get me every time. 
6. I lent them a very large amount of money to help them out with bills two years ago. They ALWAYS bring this up, asking me if this is why I 'resent' them. I don't even think about the money as a factor, but no matter how much I tell them, they still bring it up.

They manage to guilt me every single time I come back home, making me feel like a terrible son for not being chummy with them. I don't mind them, I don't dislike them, I just don't feel I have that great of a close relationship with them. I can't pinpoint a single reason to provide them with  either, it's just the way I am and when I tell them that, I feel shitty.
