Interesting Deja that your H is the same age as his mom when she was suicidal. I do think that's there can be an unconscious drive to recreate an old unresolved trauma. My ex's mom was a WAS when he was in his late teens - it was very traumatic and the boys in the family cut off all contact with her (2 of the 3 eventually re-established contact but it was many years later - one still doesn't speak to her and she's in her 70's now).
My ex then did pretty much the same thing when our kids were pretty much the same ages. Amazing that they would do the very thing that caused them so much pain when they themselves were a teen, but it's not uncommon to see here.
