Am I being too jealous

I go to a football tournament with my husband who is one of the trainers and the treasurer turns up who I know and he knows from meetings to do with football etc but she’s like ‘your husband owes me an ice cream ‘ I’m like oh yea laughing it off but the my husband comes over to say Hi to her and they are chatting she sits on my sit and they chat , but I feel like I’m out the conversation and my daughter the asks him To take her to the toilet, he continues taking to her and it pisses me off so I take her. When I come back he does even knowledge I’m back and I’ve taking her and they are all chatting parents as well.

The match starts he goes to the other side. I chat with her and she says when’s your husband gonna get me that ice cream, I’m like omg come on I’ll get you one, hope she will shut up about it. As we walk back she is like to minutes I’m gonna wind him up( talking about my husband) runs along and says I got the ice cream.

I don’t know why this infuriates me.

Then when the game is finished she’s still around and is like where’s Matt , it’s banter but her husband was there and I was there and just felt a bit silly. Whorls anyone else find this surcpisious?
