This July is my 20th wedding anniversary. I've never done anything for THIS long, except parent, because my two oldest are from a prior marriage. :-)
And yes, it's time to look at the media, and the faces you see in public, and be more realistic about what you see. We ALL put on good faces in public, and stack the "crud" in the closets of our lives. That makes everyone else WHOLE life, marriage, happiness quotient, everything, look better from the outside looking in.
My husband is pretty stable, so I get the sense that's he's more of a straight line kind of guy -- whereas my emotions zig zag like a chart of the Dow Jones Industrial Average. That said, however, he is and has been my best friend for 20+ years of marriage. We get busy, we DO live our lives around the children rather than around ourselves, but we think that's good and right. They'll be gone soon, and then we'll go to the first time in our lives of living as a dyad. Most people start their marriages that way. His job is VERY stressful, on me as well as on him, and that stress sometimes causes us to emotionally separate -- not just from each other, but from lots of things . . . but whenever I really feel like I 'just don't care" anymore, I also remember that this guy knows me. KNOWS me, my quirks, my crabby moments, my ups and downs, and he doesn't complain about them. He doesn't share them with others. He is 100% safe. He is also 100% faithful. He hasn't gone looking or found other partners, and he won't. I haven't either, and I won't. We would both be honest and faithful enough to end the marriage BEFORE we took it on the road to others. We made a commitment to each other, and even if it isn't the world's most exciting marriage, it's one of the world's greatest friendships. I can't count the number of times he's been working with other couples, and come home and said, "I am so glad I married you. I wouldn't survive very long if I were married to so-and-so. I don't know how (the hub) does it." That tells me he is 100% comfortable being married to me. I don't fuss when he works all manner of hours, I don't crab when he's tired and wants to hide from the world. I understand when he needs to be alone to unwind. And I don't complain much. I let him be who he is.
Over the years we grow into patterns of relating, that we get used to. Sometimes we call them ruts, and sometimes they feel like ruts, but they are also predictable and safe. The allure of the wild and unpredictable, somewhat new and dangerous "new" relationsip -- the falling in love stuff -- is going to call to us, because the media hypes it and often we swallow it, because it looks more exciting . . .
But the tried and true, being faithful and having someone who is also faithful, who loves you, whom you love (even when you aren't wildly ecstatic about it), and who partners with you for life, is really the better option. I've been in a marriage that bordered on abusive, I've been a single mom. I can tell you from experience that this is WAY better -- even on the bad days, than either of those options.
How close we are comes and goes, we give each other the freedom to grow in different areas, in ways that may not include us, but we always return to periods of refreshment when we definately feel "in love" -- not like when we were younger and love was new, but with a grand appreciation that this is the person we married, and we're really glad of it. The true test is to look back, and say, "If I had to do it all over again . .. ?" And, my answers, is a definate and LOUD, YES !!!! But does that mean I'm always sappily in love with him, thinking of him 24/7, my heart jumps into my throat when he looks at me ? Heavens, no! Our love is way more mature than that, I can let him go, knowing he'll be back (barring car accident, plane crash, etc), I can trust him with even the ugly parts of me, and he still loves me . . . no questions asked. He just does. And, yes, he has those "other" sides, too . . .but they are safe with me, so you didn't hear about them ! :-)
Hang in there. Don't let the media get to you -- start looking at real life glimpses of marriage instead -- it'll probably make you WAY more appreciative of your own because it fits you. (quite honestly, I rarely turn on the TV, and if I do, it's only jeapardy. I don't do sitcoms or non -reality shows. None of it is real. It's TV. And the magazines? Well, the people they interview are in love with each other one day, and bitterly divorced the next. Obviously they don't tell the truth about their marriages.) When you get to a "low" time in your closeness/feelings cycle, just look at the good things. Would you hang in with this person, just as a friend? It's way better to keep building with what you have than to walk through the pain of tearing it apart, trying to re-create your life, and trying to find another who comes to you with relational scars that may not coincide with yours.
Above all, don't be hard on yourself. He married you. He loves you. And you both love your children. .. . Enjoy them, and enjoy them together. It's way more fun, and way less stressful than the other options out there ! :-)
