Need Advice

Me and girlfriend of 4 years are “on a break” she’s been struggling with mental health which I kind of knew but whenever I tried to talk about it with her she just didn’t want to now is saying she wants space to figure out what she wants to do going forward I’m not sure if I respect that she wants space or if I should take the approach of “if you want something go get it” and try to talk to her and figure things out but that might push her even further away? Do I leave it alone and let her come back on her own time or reach out and try to talk to her figure out what’s going on? Says she wants space through rest of August
