People now have the means to act on anything they wish now. Your husband boring you? Send an message to your ex on Facebook. Tired of your wife in the sack? Make a tinder account. Nowadays, cracks in relationships are like cracks in windshields. You're gonna have to overhaul the whole thing or accept that it's going to fall apart. There's really no incentive to "problem solve" or "figure things out" any more. There's more options than ever now, and people are starting to attach values to their relationships, values that can fluctuate or be surpassed any day.
I hear girls say every day that when they find a richer, better off man, they're on to that next one. Dudes out here value getting ass and stacking chips more than spending or building with one particular person. The concept of growing and developing with one person, in a committed union, is falling by the wayside. And to take its place, we have a culture of what amounts to drive thru relationships, where we have one eye on the now, and the other looking for the next best thing.
We're in a totally different generation, and it'll be interesting to see where things stand about a couple decades from now.
