While I think it can be a fascinating exercise to figure out why we do the things we do, a lot of times it leads us down a circular path that doesn't give us any clear answers as to, "So what do I do now?"

If you are finding things "extremely boring and annoying" now, imagine what they're going to be like 5 or 10 or even 20 years from now! If he's not willing to change a little to let you more into his life, or at the very least allow your friends to come over, then I'm not sure what future the relationship holds for you.

A relationship has to be basically satisfying in all the major aspects of our lives. A relationship that works in most areas, but not others, usually isn't sufficient for long-term happiness (unless one or both of the people are willing to work on changing those areas the relationship is suffering in). So while this "friendship area" may not seem like a big deal now (although it does seem to be one from my reading of your post), it will grow and grow into one unless something is done about it now.

If he's not willing to compromise a little on this issue, then it's definitely something to take into consideration about your long-term prospects with this person. Sometimes letting our significant other just how important an issue is can lead to them understanding how important it is and working on finding a way to have both people satisfied with the issue. So try talking to him and letting him know that (if you haven't already). And let us know how it goes...
