One of you sure has a bug in your butt, because you're pick-pick-picking away at each other. If it's your partner, you should be pitied; it's no fun being henpecked to death or worn down by slow torture of the emotional variety (think the drip-drip-drip of water torture!). But if it's you doing the constant criticism thing, just what are you playing at?
You've got a good thing going, why ruin it by nagging and whining? It may seem as if you and your lover speak a different language. Neither of you can make sense of what the other is saying.That being said, you're actually in a good place to move ahead, if you can get through your rough patches. Patience is, as always, vital. Both of you tend to move too quickly, speak without thinking, do things impulsively. Slow things down a little. Make time for each other. Practice working out your problems in regularly scheduled venting sessions, rather than just fighting whenever, wherever. Before long, each of your mindsets will expand enough to hold the other's viewpoint -- and the skills you learn smoothing the path of this partnership will stand you in good stead for the rest of your life.
