I need advice...Me any my boyfriend have been together for almost 5 year...We live together, we have no...?

You must already know if the two of you will ever get married. Have you never ever discussed your relationship and where you will be in the future together? Just remember he may be a little more nervous at the thought of marriage as he has already had one failure and marriage is not the most important thing. I am always weary of relationships after marriage break downs, especially where there are other children. I think that you should just enjoy that you have such a lovely partner and that you have a really romantic night to look forward to. Enjoy it and don't worry about what might or might not happen.
