you can't scare away a man who actually likes you. you could yell, scream, ignore him, and throw a whole rock at his head. he'll still be like, "she's adorable, just a little angry today."
I read somewhere that "When you choose a life partner you're choosing your eating companion for about 20,000 meals, your travel companion for about 70 vacations, your retirement friend, career therapist, & someone whose day you'll hear about 18,000 times" and I really can't stress this enough.
