Leaving soon. Need reassurance.

I’m planning to leave really soon. Plane ticket is purchased. I’m just looking for last minute reassurance I’m making the right decision. I will put it this way:

If someone acts one way more than several times in 5 months of marriage, it’s likely a pattern that will repeat itself, correct? Meaning, if I’ve seen my husband act narcissistic, abusive, selfish, and intimidating at least several times if not more, then I’m not imagining it, correct? I know I’m not. I think this is normal last minute guilt trying to stop me from leaving. I won’t let it.
