Re taking a break
It can be incredibly hurtful and confusing when we feel the person that we love pull away from us, and can bring out all sorts of insecurities and paranoia. Your girl has a very good reason at the moment, that she just doesn’t have the emotional space for anything else at the moment while she sorts out this mediation issue, but that doesn’t make things any easier. Despite how you are feeling, I think that you need to show her that you can put her needs above your desire for contact etc in this instance and respect her wishes. By all means, you can make it clear to her that you are there for her if she needs anything, but I would step back and show her this side of you. I think it can only work in your favor in the long run.
