Naimbia chooses the wrong targets to be angry at because she makes bad choices and blames the wrong people for those choices.

She chooses to be with a man who does not value and honor her and uses her. That is her choice and instead of realizing she chooses this man she blames not even the man but his girl friend. She has no ability to place blame on herself or the man, it's placed on this other woman who of anyone in this picture seems to be the most innocent she had the guy first.

She chooses to help the lazy Antonia on a project Antonia was screwing up. Antonia failed to get out of bed and get started. She put no effort into getting organized and getting the room prepared. Since she doesn't feel she has to put forth any efforts to be polite and respectful to her housemates she didn't approach them in a reasonable time frame about the project and explain what was going on or what needed to be done she just whined to Niambia about it. Niambia then chose to enable Antonia's bad behavior. She knew Antonia had chosen badly, screwed up and should face the consequences of doing so but chose instead to try and bail her out at the last possible second. Now that was her right to do. However, after playing the martyr and choosing to again be an enabler as she is with Mr. Situation does she get mad at herself or Antonia because she is being taken advantage of, no she gets mad at the other HG.

Did she ask Antonia why she didn't come to her first thing in the morning when they could have approached the hg together? No it's always easier to play the blame game then to actually realize poor choices lead to bad consequences.
