Desde cuando sintiende con ella
I know sintiende shouldn't make sense but that's what it sounds like. What could it mean? How long have you felt for her?

"¿Desde cuándo se entiende con ella?" How long have you been "having an understanding" with her? As Margaret correctly surmises, this is a rather formal and old-fashioned way to ask the question that you already understood.
Could it be 'se entiende'? - Sounds old fashioned to me - like 'how long since they came to an agreement (to marry) to be engaged, or whatever' .
Well, he definitely said "how long have you felt/been in love with her" because I've seen this show in English. But I wonder about the form.
