Continue living in the real world.
Congratulations! Your relationship is absolutely standard in at least one regard: it's not a non-stop roller coaster ride to a planet of thundering orgasms and sublime romance.
I usually think people tend to rely on their partner too much for happiness and fulfillment. If you're relying on your partner for constant entertainment, you're bound to be disappointed. Because let's face it, most of us are boring as hell.
If you like and care about your mate, then it sounds like things are going fairly well. Don't over-analyze or throw things into question just because you're not a hundred percent balls-to-the-wall happy right at this second.
Sharing your life so intimately with someone else brings with it a bit of everything: boredom, enlightenment, frustration, trust, familiarity, confusion, respect. It's not homogenous and it's certainly nowhere near as entertaining or coherent as your average primetime television drama.
So if you're bored, don't look to your partner; plan an event, read a book, take up a hobby. I hear international political assassination is booming this time of year.
"Because let's face it, most of us are boring as hell."
Sooooooooooooooo, true!
Probably even more so for us funny/crazy guys. Those of us who are "high strung" out and about with our friends are often super mellow in our downtime. It's not that we are misrepresenting ourselves, it's just about cycles.
Hey, if there were no boredom, then how do you know when things get exciting? It's all relative.
I'm taking a stab in the dark here to say that I think I have been married probably longer than you have been alive and there is one thing I have learned over these many, many years - everything in life is cyclical. You have life & death, O2 & CO2, children moving out & children moving in, weight gain & ...well, that one usually doesn't work, and you have boredom & excitement within your relationship. Trust me, I've been through it many times, and then we find Cosmo's latest sex position and BOOM! excitement is back - sometimes even in the form of an ambulance ride to the ER. (Thanks Cosmo!)
Seriously, I think boredom is nature's way of making sure we're still thinking. Boredom sucks, therefore, we tend to do things to get out of it and this usually drives us to try new things, be adventureous, take risks, get that adrenaline pumping. And Michael is right, don't be looking to your partner to keep you entertained - take a stab at something new, maybe something you have always wanted to do, but never had the time.
The other thing I have learned over the years is to remind myself that this won't last forever. And sometimes that is bittersweet. Good luck!
