DH (43) and I (39) live in a big town, where he grew up. He has had a tight friendship group since he came back from uni, 3 guys and 2 girls, who were all very close and follow the town's football team regularly.
In their 20s, one of the girls met a guy and moved away. This was before I was on the scene. She is still in touch and I have met her, she came to our wedding, but isn't around in person much. The other 4 were then like peas in a pod for over a decade. Partners would come and go, sometimes stay, weddings happened, but the four of them stayed very close.
I met DH nine years ago and we got married 6 years ago, just before COVID came along. We have two young children. The other two guys were his two best men at our wedding. He is a great dad and husband, he has a good job and we have a good life. Although he is football mad and used to go to pretty much every game, home and away, he has limited how often he goes since the kids have come along. He still goes regularly, but that's always been his thing and I have never had an issue with it, even though I am not into football myself.
However, the dynamics of his friendship group have changed. Three years ago, one of the guys split from his wife and moved to Canada for a work assignment. He has met someone there and it doesn't look like he's coming back. Then two years ago, the other male friend was diagnosed with cancer. He passed away early last year and DH was devastated.
So now DH and the remaining girl are the only ones left in the group. They regularly go to football together. They have history - they dated in school (like age 14-15 so not serious) and slept together twice when they were in their early 20s. DH has never hidden this history from me and always insisted that they were never serious, any attraction was long in the past, and they are just close friends. I have never had reason to doubt him.
But now it's just the two of them left in the group and they spend a lot of time together, driving to away games etc. She is single with a string of bad relationships behind her. DH is the one she calls when things go wrong.
Over the last 6 months or so, I have found myself getting jealous and paranoid. When they were a group of 4 or 3, it honestly never crossed my mind. But now it's just the two of them, and the way she looks at him... I am sure others will know what I mean? I am sure she has always had feelings for him.
I tried talking to DH and he said he understood but he has lost one of his best mates and now she's all that's left from the group. How can I ask him to give that friendship up? He said if I was concerned about them travelling together then I could come along, but that would involve childcare arrangements and I have never been to more than about 3 games, I feel like it would be weird if I suddenly pretended to have an interest in a sport that bores me to tears. I don't want to be the wife that tags along to make sure her DH isn't f**king his friend. I don't know, I am emotional and lost. Mainly just scared. Sorry if this was long.
AIBU to be losing my mind over this?
