This is so beautiful and inspiring. I’ve had attachment issues before; in every relationship prior to my current one, I’ve been anxiously attached, or, worse, anxious-avoidant (also called disorganized attachment style.) this was a result of not just upbringing but choosing people who were strongly avoidant. In other words, if I made a bid for attention, I never knew how it would be received. I had one parent who is an emotional black hole and another around whom I would have to walk on eggshells for fear of her temper. And then I had abusive exes, so that was a whole other thing! However, with my current partner, I have a secure attachment. The key here is to CONSISTENTLY respond to each and every bid for attention. When that happens, the need for attention actually subsides. The anxious partner can feel sure that their significant other will always be there, so they don’t need to “check” as much. Usually women are the ones who are anxiously attached; there’s just so many expectations of us in today’s society, so many standards to live up to. Who WOULDNT occasionally feel the need for reassurance?! But sometimes men need reassurance, too. And loads of women these days are declaring that they’re happier single, just because dating and being in a relationship can be so stressful. But it doesn’t have to be. Just RESPOND when she needs you to. And if there’s a misunderstanding, hasten to clear it up, and not in a defensive way, either. Do these simple things and it’s (generally) smooth(er) sailing!
Also, having similar senses of humor is SO important. So is honesty. There’s so much in what you said that I relate to! It sounds like you were an amazing husband to her, and I’m sure she loved you very much. While it’s obvious to everyone that you miss her terribly, I do think she would want you to move on and to be happy.
