Sorry to post this again as I posted it in chat but didn't get much response and I would appreciate some advice on this. I have been with bf nearly a year and kids have met him quite a bit. Bf came over earlier and as son was coming downstairs to say hi bf started saying he's a good looking kid but needs to sort his attitude out - kind of to me kind of to him but son (9) only heard the second half of it. Bf apologised and later said it was just banter but I have said it is not acceptable and he has now gone. Would this be a deal breaker for you? There have been a couple of other times where bf has reacted negatively to my son's behaviour and had shouted at him once and told him off another time- though i had not fully seen what had happened in the run up - was in the same room but distracted. I am worried if he could be like this at the relative start of the relationship then it could escalate. I would never say anything like that even to a parent of a child let alone in earshot of the child even if I did think that about the child and my boy is really very well behaved overall anyway (not that that is the point) Am I being over sensitive?
