Working for a temp agency can be a good thing for a while- they do take into account your degree and your particular skills, and they try to match you up with relevant temporary jobs. Often such jobs will lead to something else, or maybe even open new ideas to you for other things you might want to do.

If I recall correctly, it was your boyfriend who wanted to make this move to begin with, and you quit your job to do it, so (in my humble opinion) leaning on him financially for a month or two while you get a new job doesn't seem that unreasonable to me, especially since he makes 3 times as much as you do.
