Have you ever noticed that a good many relationships, if they last past the first couple of months often fall apart sometime between the first and second year? My theory for this phenomenon is that most guys, at this point take a serious look at it. And they think about marriage. And either they say yes or no.
At about the one year mark, a guy's been in a relationship for awhile. They don't know this until one day, they say holy cow! This is getting serious or something! And they think to themselves, what do I do? Do I want this to be serious? Or do I want to play the field some more? Inevitably, thoughts turn to marriage. Am I going to be happy married to this girl? Or more to the point, am I going to be happy married? This is going to be the last girl I ever screw......can I handle that? A guy will ask himself these questions. Maybe not consciously, I don't know. Maybe it'll all happen in his subconscious. But I think that these questions do pop up. Haha, catch that bad joke? Anyways, many times, a guy will say WHOA hold up here baby, I'm getting OFF this train before it's too late. And generally it won't be because the girl is no good or something. It's because he's worried about marriage. About spending the rest of his life with this girl. Doesn't want to limit his options. So he breaks up with her. I've seen it many times. It's too bad that it has to happen like that.
So, say the guy asks himself these questions, and finds himself ready and willing. Generally, at that point, he's ready to get married. Now, that's not saying he's going to do it right away. But he's faced the idea, he's cringed and he's shuddered, but he's still standing. Now it's just a question of time. It's still very possible to have breakups at this stage of course. But such breakups are more kin to divorce than to a couple breaking up who's been together for three months or something like that.
So, women, once you get past the 1-2 year hump....everything should be okay. Of courses there's also guys who like to put off the decision, thinking that if they wait long enough, it'll go away. Get rid of those screwballs. If they don't know that they want to spend their life with you after a few years, then they're pretty much going to be a wash anyways.
And of course, I realize that my quick and dirty look at this trend isn't going to encompass all guys. But many.
