DH is 46 and we’ve been together for 10 years and have one DD. He’s a good husband and father, has never given me any reason to doubt him.
We’ve always had separate hobbies and for DH those hobbies are hill walking/hiking and running. He always runs alone, but his hikes are either solo or with male friends (usually the latter).
A few months ago, he mentioned he was doing a 10k with someone from work, who was also into running. She’s female, 25 years old. He was completely transparent about it, said they are friendly at work and they agreed to both enter the event.
Anyway, he did that, and all was fine. However, since then the friendship seems to have gone up a notch. They’ve got another 10k planned, and she’s never hiked before, so he’s suggested she tag along on one of his solo hikes at some point.
I have actually met her, briefly, after the 10k, and she was perfectly pleasant, and there was nothing from how they are with each other that made me particularly suspicious. However, I can’t get over the nagging feeling I have that I should worry somehow, or the friendship is odd.
He's completely transparent about everything and there’s no other suspicious behaviour. In fact, he never mentions her other than in relation to the runs. I’ve not told him how I feel. He’s always looked younger than his age and has a youthful energy (for want of a better word), and I’m worried there’s more to all this.
AIBU?
