LaMorena-

  My friends have all given you very good advice.  I would like to add a bit.

 In regards to your boyfriend...Many times, when people become workaholics, they are running away from something very significant in their lives.  The constant work serves to keep their attention away from issues that they would rather not deal with.  What you are describing is very, very extreme and, except in situations of dire financial hardship, could be considered, disfunctional.

 You have given us a very strong sense of how difficult his behavior is for you to deal with.  I cannot say I blame you.  I think alot of us assume, that when we marry, we will be in a relationship where we are there for each other and work towards common goals. This is definitely not happening here. 

I would strongly suggest premarital counseling for you and your fiance.  As others have said, it is very unlikely that any of this will change after the wedding. The issues that are causing your boyfriend to behave this way need to be discovered and dealt with or there is really no hope for your future together.  Together is really the key word here.  At this point, there is no together at all.
