Welcome Eddie- glad to have ya around. The forum is open to everyone.
There will probably be certain moral standards you'll have to abide by to attend college there, but you don't have to convert to LDS.
But if you're interested in learning more, we're more than happy to help out.
It is expected of young men in the church to serve a mission to where they are called- but you don't have to swallow that right away. It can be a scary thing for many parents to send their kids to some far off country. Sometimes the fear stops them from serving a mission. It takes great courage and faith.
Divorce is allowed in those cases, I would say even encouraged as the right thing to do sometimes. All cases are unique though- there's not a one size fits all answer.
Some girls won't date you if you're not LDS- and some parents won't allow their children to date non-LDS. To be honest, I personally would be real careful about letting children date non-LDS- it has to do with our beliefs about temple marriage, which is only available for members of the church.
