How to deal with my passive aggressive roommate?

I've dealt with a situation similar to this. For me, my roommate wasn't worth my time so I just ignored her and kept on with my life until she eventually moved out. If she isn't willing to be grown up enough to air her grievances, then she doesn't deserve your time of day.

But if you really want to talk it out the best way is to do a small kind gesture like bringing her a small gift, just to disarm her. Then, just sit down and say you got it for her because you sensed some tension and it worries you because you used to have a good relationship.

Or if you're even less inclined to speak with her because you think it might blow things up, talk to your other roommate and she if she knows or if she can help you out because she probably has a better background on the situation.

Say to her, "Roommate, it seems like something's been bothering you lately. Did I do something wrong?" See what she says. If she ignores the question and keeps being passive-aggressive, ignore her. Act like she's not even there. There's no reason to engage someone who's obviously not interested.

Soo many people have this exact same issue! It can be difficult if your interaction style is to talk to those around you. Mine isn't - I only talk to people when things are going really well.

The minute that changes I talk to no-one and don't even make eye contact. I prefer to live alone so it's not an issue.

Maybe have a roommate meeting and see if that resolves it.
