It's normal to have doubts, but I do think that if you marry someone you have to have the feeling of 'this is the one'.

I've never had that feeling with any woman I have ever been, which is good, because I would make a lousy husband. However, I've had a few narrow scrapes and almost got married (twice), but thankfully I never did.

You haven't said how old you are. I really believe age is a major factor of whether or not to get married. If you're under 27, I would say wait until you get a few grey hairs before getting married. Remember, being a man has its advantages. We get better looking as we get older and we can date women younger than ourselves too.

In any case think hard and long before deciding to tie the knot.
