Spending time with some friends

It is It's (*not necessary, but people tend to use this type of contractions most of the time in non-formal speech) always good to spend some time (http://www.funkyenglish.com/page/sometimes-some-time-or)  with someone we don't speak haven't spoken with for a while.
Right now I was talking to a friend that I don't see him haven't seen (look up present perfect) /OR could use "that I don't see" w/o the "him", it's less proper, but valid) for a month, I think...
He told me about a party he went to last weekend. It was a wedding party. At the party the couple danced a song very known here, it's called "valsa" (comment: that's called "el vals" over here! :) ). It has been one of the most fancy dances I have saw seen in my entire life. Beautiful movements throughout the room. People love this kind of dance. Now people have spent a lot of money on wedding parties. I would prefer spending that money with an in an amazing travel to europe or the US, for instance (me too). My friend agreed with me. It's common we have the same opinion about the same subject. We used talking used to talk about some interesting topics when we had more free time to talk to each other. Now our day by day avoid prevents us to meet from meeting regularly. I told him we need to change it and one more time, we agreed to with each other.

Thank you for your corrections.
