This may be a cause for marriage difficulties, and yet the article also suggests that over time people can work to improve their attachment styles:
Article from Yahoo Life: WashingtonPost:

- Securely attached people generally trust others and feel comfortable with both intimacy and independence.
- Those with an anxious attachment style often crave closeness but worry about rejection or abandonment.
- Avoidant individuals tend to prize self-reliance and keep an emotional distance, even from those they love.
- And people with a disorganized attachment style may swing between seeking connection and pushing it away, reflecting conflicting expectations about whether relationships are a source of comfort or danger.
And here is an older study (on Pubmed), and the only one study that I currently found online, about shifts in attachment styles:
If new research was done now perhaps there might even be greater shifts in attachment styles, since Covid-induced patterns of isolation. And I would guess that the more "avoidant" and "disorganized" attachment styles are less likely to marry. But this is just a guess.
