It doesn't sound like jealously. It sounds more like pure misinformation. I dont like to talk about hair with others who dont understand my hair interests and concerns.
People beyond this hair board find certain hair practices bizarre and potentially dangerous to your hair and theirs. So your roommate's comments do not surprise me.

She said that I didn't really need neutralizer because I hadn't relaxed my hair in so long that it wouldn't make a difference..

.. I use to get commentary from my suitemates when I washed my hair.. my same roommate now was the one who always had a comment about me washing my hair frequently, always having it wet and airdrying, stretching my relaxers for 6months..blah blah blah... pay her no mind.. and continue to do what you do.. she'll always have an opinion ..when your hair is WL and beyond..she'll be in there trying to do a treatment or 2 herself.
