Facebook is not the place to do that.
I've noticed a trend in seeing my friends posting sweet nothings on their significant others Facebook wall and it makes me cringe. I grew up getting cards telling me how much my parents love me (and to this day will get at least 4 per occasion...one for me from my mom, one from my dad, one from my dog, and one for Tyler and I from my parents) and although there are times I think it's overkill, I still enjoying getting those in the mail knowing that they took the time to actually go to a store, read through a bunch of cards, underline what they want to emphasize,
put money in them, and mail them to me. It means something to me. I do the same for Tyler. Cards are a must for every holiday - he found out the hard way this past year on my birthday and hasn't missed since!
When I see my friends posting on their husband's wall (because Facebook makes me) sweet nothings about how much they love each other, how they couldn't imagine life without them and how they can't wait to spend every single day together for the rest of their lives and have babies and grow old together and on and on and on...well, it sounds forced and in my opinion, cheapens the actual sentiment behind it. I mean, come on ladies (yes I'm talking to you, we all know most men aren't doing this), you LIVE with the guy and you're going to see him in 4 hours when you're off work. Can't you send him a text or give him a card if you can't say it to his face!? if you find that you can't actually say it to his face, you've got other issues. Getting hammered drunk might help though. You don't need all 400 Facebook friends to see how much you love each other via your Facebook wall posts. Unless you're trying to prove a point to someone that you know is going to see it...which makes it even less meaningful.
I know that you love your husband (or boyfriend for that matter) - you're either MARRIED to him or living with him so I get it, I don't need to see it on Facebook. If you must show the Facebook world how much you love each other, do it with pictures (PG though, save the X-rated for another site) or your relationship status.
It takes just as much effort if not more to login to Facebook, find their page, get to their wall, type the message and hit post. How about picking up the phone, hitting #2 for speed dial (your mom should be first) and telling that person how much you love them. Or go the extra mile and write an actual note, like on a piece of paper or grab a card the next time you're at Target. Then pick up some of his favorite candy to go with. He'll probably do the dishes that night for you. Doubt he does that after your Facebook post.
So please friends, think before you post next time. If it's something like "hey, forgot my phone today, can you grab some spaghetti on your way home? Love you!" that's one thing. But "Oh my god, you are the best thing to ever happen to me, I love you so much, I'm so happy we are together..." - wait until you get home and tell him face to face or shoot him a quick text message if you just can't stand not telling him for 4 hours..or 2 minutes since he's probably just in the bathroom and all.
