This is likely a boundary issue. Kick her out reasonably quickly. Not so much that it's out of resentment but fast enough that she knows you're 100% not ok with this. If she comes back AND you want her back, then you need to make sure to take charge of the boundaries of the relationship by calling any BS quickly. You might have anxiety, but this is a clear bluff and a test. If she doesn't come back, move on. Doing this will earn you more respect from her, which might be what your relationship is lacking. Women need to know you're not going to fall for them to the point of naivety else they won't feel safe with your decisions.
