What dimensions matter for relationship compatibility?

Personality (Big Five traits, not MBTI), values (aligned on kids/money/meaning), attachment (both secure or both working toward it), life goals (do your futures align?), communication skills (can you fight fairly?), and sexual compatibility (are you on the same page?). Strong across 5/6 dimensions suggests lasting compatibility.

How do I assess compatibility across these dimensions?

Formally: take Big Five together, discuss values explicitly, consider attachment history, ask about life goals directly, practice conflict conversations, and be honest about sexual desire. Informally: observe how they handle stress, talk about family, prioritize you, solve problems. Multi-dimensional assessment beats single-metric tests.

If we're weak on one dimension, does that mean we're incompatible?

Not necessarily. Strong on 5 dimensions, weak on 1 is usually workable. Weak on 2+ dimensions starts signaling incompatibility. But context matters: weak on sexual compatibility might be fixable through therapy; weak on values usually isn't. Identify your weak dimensions and decide if you can address them.
