A lot of people go into marriage with different reasons. Reasons ranging from what they will get or how fat their pocket will be during the marrige journey(money), some others go into marriage just about the physical attractions amongst other things (tall dark and handsome; slim, fair with killer shape).
The thing they fail to consider is, what if all these things aint there anymore, what happens next? What if the money isn't coming as it should or the person gets a scar or looses the shape you so loved, will the feelings still be there for them?
Have you ever thought about why your friend don't seem ugly to you, even when others say he or she is ugly, you still don't see it? This is because something brought both of you together and then you became friends, felt compatible, so other things fell into place. This is how a relationship/marriage should be.
Like Barry White sang "baby I love you just the way you are", love him/her the way they are. For better for worse isn't beans. Remember to help him/her become the better person you want them to be. No, I don't mean change the person, that isn't easy either and many people may see it as offensive, I mean guide them to the right part. Please don't get swept away by physical attractions, yes we all know that something draws us to a person, but you shouldn't make the less important things a priority. Note that a successful relationship/marriage needs more than that to sail into higher grounds. Be wise. Ciao.
