Most Helpful Girl
Its easy from an armchair. Its easy when we are not in the situation to be like "hey, this dude is a jerk." However, things appear differently in context and in the situation, that definitely make the lines of logic fuzzy. Plus, we don't have feelings associated with the other person, whereas, the person in the situation does.
Some girls just have low self esteems and don't know that they can be treated much better.
