??? Is this normal “discharge”?

lately i keep getting this, it isn’t even wet? it’s kinda crunchy. idk how to explain….. got it outta nowhere. also this might be random add on but been dealing w problems w my bf due to his once, but still happened online betrayal and unfaithfulness. he promises it wasn’t anything more than online but… i have a gut feeling something is being hidden or he’s lying. could that contribute to this ?? idk i’m lost n confused.
