Hypothetically, if you were texting a girl you love and she was being down on herself, so you try to flatter her and shower her with compliments, and then she responds with "No, I'm not any of those things, you need to stop"
Hypothetically, just opening a hypothetical, honest line of communication about how you hypothetically feel about things hypothetically solves most hypothetical issues.
That's cute disney advice, but not how the real world works. That is of course the first thing I would try.
Ya dude like love is great and compliments are also great but don't go overboard because it can push a girl away real quick because it does stem from some form of insecurity on their part. Way happy for you tho gl
