it is not like she has actually promised to carry me for sure ...

About the Apprehension about girls , I had a lot of problems too with this girl before we got married, here in India many people get an arranged marriage where parents take decision (though this tradition is eroding fast), this was the reason we could not back away from the marriage , but now no regrets after getting married, the girl is getting along with me just fine
