Every roommate I've had in college (6) left/ requested a room change after the first semester. I try to objectively see my living habits but don't think I infringe on anyone, especially when Id be at work or school. Currently I live in shared housing and have alienated a majority of my housemates,  often without being told why or have not interacted with them enough to be disliked.

 Some of them I would hang out with daily suddenly stopped talking to me and even actively avoid me or if they see me sitting outside, they'll immediately go back inside and slam the door.

The only complaint I know about me is that I'm inconsistent with doing the dishes.  at this point I just keep to myself to ensure there is no trouble.  Of course, this makes it difficult for anyone to care about me, but since it's much more common that I'm shunned, im happier with a position of keeping to myself. 

I see myself as being helpful, generous, a good listener, honest and reliable. I think those are good qualities... But I'm not sure what my bad qualities are that people go to the extent to actively shun me, avoid me, or pretend I don't exist 

I would often offer help or share my things with the others but often times my offers would be rejected.  The others also don't share with me or return favors or whatever.  Not that I do nice things because I wabt them in return, the point is that I'm trying to share and include others but it's not appreciated and I'm excluded.  


What can I do to further understand what I'm doing that people dont want to be around me? 


Of course I've asked, but was reassured each time that "it's not like that" or they are "busy" or that they aren't aware of a problem. so I don't have anything to go off of as far as understanding ways in which I don't get along with people. 

Tl; dr how can I learn why people abhor me or dislike me?  I don't know how I'm alienating them.
