My son refuses point blank to see his father and extended family due to father's behaviour to him over the years. There is no court order although when younger there was a standard shared visitation schedule in place. Sons father is getting married again, a destination wedding at the end of this year; meaning to attend would likely be around 4 or 5 days minimum dependant on flight availability, son does not wish to attend and has made this clear, yet is being hassled by other family members about this; creating more strain on any future relationships with them. He is 15 and very clear on all of the toxicity he endured at the hands of his father over the years mainly due to alcohol addiction and does not wish to be coerced into ultimately a long weekend or week long trip with them. Thoughts please.
