Go and touch the grass, few times. I have no effing idea what situation and judging based on vague information you provided i couldn't determine whether Jason is pedo or engaged very morally questionable romance, like maybe they had light relationship when she was 15-17 years old and everything mostly began after 18... Both things are bad, btw.
You not gonna win people trust when you insult them just because they had some amount of uncertainty in their response. If something obvious to YOU it doesn't mean it's obvious for OTHERS who don't know the situation.
If what's you wrote, in message to what i am replying now, is true then he is indeed pedo. Period.
