She pretty much stopped messaging me and replies in one-word sentences. I asked her to meet tomorrow and she simply said "I have plans" which I know she doesn't. I replied "ok, let me know whenever you want to meet" and she hasn't said anything else since.

Forgot to add this plate asked me for exclusivity earlier this year which I agreed to but then she wasn't really offering a girlfriend experience so I didn't think she deserves my commitment

I know she's acting like this because of that one pic with another girl. Can I save this situation or should I hard-next?
