Bless you. The only way to tell is to wait a few days and do another test.
I will say though, my understanding is that evap lines on pink line tests aren’t very common. You’re more likely to get an evap line on a blue line test, especially in the early days as they’re generally not as sensitive to hcg as pink tests.
Get a First Response Early Results test, and do it in a couple of days.
Sorry to hear about your relationship. You do have options if this isn’t the situation you want to be in.
