Boyfriend of 3 years and I have nothing in common I feel Lost what should I do?

My boyfriend of three years and i seem to have verry little in common. I enjoy nights out that are fun, high-energy,(dancing hanging out with friends club hopping meeting new people ect.) he does not enjoy these things and when we do go out i feel dragged down b/c he is not enjoying himself and i feel bad b/c i know this so we leave early like an hour after arriving. going out for him is going out to dinner movie and arcade mabey some shopping for video games or movies. so we seldom go out b/c i am not the videogame/arcde type (i end up very bored and sitting down with a book. we very seldom agree on movies to watch as he has a very select few that he likes or catches his interest to try and most of them are what i call stupid-funny movies not like truely funnie movies. so i usually end up watching t.v. in the other room or reading or getting on the computer. we very rarely watch t.v. together b/c there are only a select few things that we can agree on. I hate most of what he watches and he cant stand most of what i watch.(he is a south park/futurerama/in living color type I am the law&order/house/charmed type). even choosing restaurants i usually default to him b/c i like a variety of food.(mexican, thai, japaneese, korean italian.......ect he is steak and spaghetti). i enjoy reading he enjoys videogames. I dont care for video games he couldn't care less about books......i enjoy at least trying new things he is stuck in what he already knows he likes..........our differences don't stop there(everything from cleaning to childraising). I enjoy talking and spending time with friends but any time I talk to the couple that i still talk to (granted they are mostly guys) he dosen't say anything but becomes noticably upset. I feel like I am losing myself trying to make him happy. I love him and don't want to hurt him, my daughter or his 2 girls, but, I am not sure what to do.........
