Women, if a guy you havent seen in years wrote you letters, how would you feel

Like maybe some of the letters were romantic, some of them were just platonic but all in all they were essentially to let you know what he's been up to and him wondering what you've been up to for years, let's say 3.
He knows you're not a romantic option and he knows you have someone but he just likes making his feelings known and letting you know stuff regardless.
Would you find it creepy and weird or more nice and sweet?
