attraction can definitely grow, suzan.
if you genuinely like this man and feel he would be a good partner for you, you may very well find his attractiveness increases the more you learn to love and respect the inner man.
i have never, not once, had a decent relationship with a man i was physically attracted to from the outset.
so i've learned my chemical responses are no judge of who is kind, considerate, faithful and mentally compatible.
look around you. many, many, many very ordinary looking people have happy and passionate relationships. someone took the time to get to know them and now finds them adorable.
don't let a good man slip through your fingers until you're SURE he's wrong for you. i don't think you are, yet.
kiss him. see how it feels. then kiss him again. and again. then maybe kiss him again.
and oh go on, just once more. with feeling.
