Experience teaches that chemistry does not automatically equal compatibility.

The pull toward someone is real information about attraction and almost none about whether life together would work. Values, rhythms, how conflict goes, what each of you wants the years to look like: none of that is measurable by how electric the beginning is.

Early on, watch the ordinary things alongside the exciting ones. How they treat people who cannot help them, how they handle being disappointed, whether the practical parts feel easy. Chemistry gets you interested; the rest determines everything after.
