My IC says there are 3 different types of communication problems in marriages. My H and I fit the pursuer/distance problem, which she said is actually very common and fixable.
Like you, my M also had problems - we were married for 20 years, so, of course it did. But, marriages have seasons and, just because it gets hard, you don't bail. You marry for better or worse and you do your best to fix the problems before you take the drastic step to get a divorce. Yes, it might have been easy for our H's to walk away because it was a rough "season". But, that is just an excuse not to put in the work.
You are where I was last Wednesday. I was talking to my IC and said "maybe H is right, maybe our marriage did stink and we should get a D". She said everything I just wrote to you above. And, you know what, she was right. All marriages have their issues - no one has the perfect marriage. It is all about how much the two people in it are willing to work on it.
