I am going to be going to grad school in the fall at a state school, but I am not a resident of the state my school is in.  My boyfriend is a resident of the state, and after trying to find a way to beat the system and get in state tuition the only way it seems possible is if I marry someone who is a resident of the state.
My boyfriend and I have been together for 3 years now and have been living together for 2 of the 3 years.  We are extremely happy and were planning on getting married eventually anyway.  
When I was talking to him about my financial situation I mentioned jokingly that they only way I could get instate was if I got married.  He looked at me very seriously and said "Ok".  I was completely taken aback because I had thought he didn't want to get married until we were both settled down with jobs and a home.  
He suggested we go to the court house and get married but not tell anyone we were wed because he still wants to have a ceremony and reception for our family and friends.  
I told him I had to at least tell my mom because I wouldn't feel right about this at all if I didn't.  When I told her she got extremely upset and hasn't talked to me since.  
I know it may seem like I'm marrying him to get a break on tuition and while it is nice, being married to him is something I've dreamed of for quite some time.  
Because I can't talk to any of my close friends about this I could use any sound advice at this moment.  Thanks!
