Yeah, I don’t think playing that word game with your ex helped you any, even though it felt good at the time. It sounds like it ended up pulling you backwards a bit. That’s happened to me when my ex has contacted me, too.  It gives you a weird sort of hope, only for it to fall flat. I think you’re doing the right thing by not contacting her, though, because she showed a lot of immaturity still over the past few weeks.

I also think you should quit beating yourself up over why you don’t feel like this with your girlfriend. It’s VERY likely you don’t feel like that for her because your girlfriend isn’t a match for you. If you found a woman who IS a good match, I bet you’d feel those feelings for her and your feelings for your ex would start to really fade more. So there’s no point in feeling like a jerk about how you don’t feel or remember things with your current girlfriend… you cannot help how you feel or don’t feel. Those feelings just show you that she isn’t the one for you, especially since you’ve been saying the same thing for months now.

You HAVE put yourself in quite the situation and it’s going to take a little time to be able to get out of it, given that you don’t want to make your girlfriend move to another family member’s house, so you’re just going to have to try to do what you can to help her to be able to move and, hopefully in the next month, with tax season, she’ll be in a better position to move out.
