Should I marry a guy who s a little shorter than me, but for whom I have a lot of consideration and affection?

I am 30, I had all sorts of disappointments in my love life so far and seldom met guys who were right for me. Now, I know it seems shallow from me, but I met this guy who s 35 and wants to marry me, I know he is serious, warm, loving, and wants a family. I really like his character and the way he makes me feel, sometimes I think I might be in love, however sometimes I feel awkward because I feel physically we don t look exceptionally good together. I am 5 ft 9", he is maybe 2 or 3 cm shorter than me: generally speaking I have never been crazy about his looks, but drawn to his way of being. As superficial as it might seem, I always tried to let physical attraction on a second level and it keeps coming back to me like a boomerang and I keep getting hurt. My sis tells me not to go out with guys I am not physically attracted to anymore bcz I keep getting hurt, but for some reason tall atractive guys don t ask me out, or if they do, they just want brief adventures. I would like to settle down, tall attractive guys might never appear. On the other hand, I have doubts about this guy, but doubts have only to do with his height.
