I've been with my boyfriend on and off for about a year now, he has children from a previous marriage and after planning to spend Christmas with me, my father and sister, he changed his mind yesterday, suddenly saying he really wanted to visit his children on Christmas Day instead (2.5h drive). I constantly empathize with the fact that he wants to see them and actively encourage it, but I also cannot help feeling let down by the last minute change of plan.
A row ensued, as I was accused of not trusting him, and not respecting him. I just wish he had not made plans with me, to let me down. He will return in the evening but I am (probably not justifiably, but naturally concerned nonetheless) that Christmas Day with his ex wife and lovely children will make him want to return to his previous life. He hasn't returned to her but has said he thought about it for the kids sake when we split up briefly earlier in the year. He tells me he loves me and we rarely argue but he loves his kids more than anything.
Am I being silly? Selfish?
Thank you in advance for responses.
