Back to the topic at hand…. 🙂
It is normal to be nervous – if you were not nervous, something would be wrong. I don’t know where you are, but if you are in Israel, contact me off the boards and I can refer you to someone to talk to before you get married.
One thing to remember (I am coming up on 18 years of marriage) – try and always think how you would feel if what you just said/did to someone was said/done to you. It can really change your perspective when things get rough (and they will!). Marriage is good, but it is not easy. If you keep that in mind, you will be fine.
Mazeltov!
