His behaviour is certainly inappropriate, but take a quiet moment to try to find out where the anger is coming from

My partner and I have been together for 25 years and we have two sons, aged 14 and 16. Both are football crazy and have played since they were very young. My partner’s competitive nature was one of the things I initially found attractive about him (I wanted someone with drive).

However, this side of him rears its ugly head when our kids play matches. He shouts, criticises and, worst of all, swears at teenagers. I’m so embarrassed by it and it’s also affecting the boys. Their teammates hear their dad and it’s creating tension. I’ve tried to speak to him about it but he brushes it off. Our boys and the coaches have spoken to him too, but to no avail.
