What people should or should not do is always based on the rule book in accordance with the society to which we were brought up.

It is not a relationship based on sex, that is something that is growing and improving with the mutual enjoyment of each others company, and with that a gradual but true love.

There are couples that are engaged for 6/7 years that get divorced after a year or two of marraige, so why wait if it is something I have not yet tried, I don't have much to lose and it conforms with the culture of her family - the one who have been my hosts.

I am assuming that the divorce rate is higher in the west tha it is here and that more effort is put into a relationship.

Physically, I still look at her with the same awe that I did from the start, and I know she won't stay like that for long but now the actual and genuine love has started to develp after 4 months, that doesn't matter.

On Slimboy's thread somebody said something about familiarity and security keeping a relationship solid even after the love has idled into like, or even tolerance.
That's all very true and good too. You're being real. Ignore the cynics and go with what seems right to you in your unique situation.
