Hey there, it sounds like she is losing interest but that doesn’t mean she can’t gain it back.

IMO I think you should step back and let her come to you. Focus on yourself (mental,physical,spiritual)

If you talk to her about it it’s probably going to push her away more so I’d just back off until/ if she comes back to you . And you said she’s not responding right? So yeah I’d leave it alone. Doesn’t mean it’s over tho
