Lost and looking for help

[BC39]

So on the weekend I'm on our computer at home and see on the internet history from day before that W searched OM name while she was on business networking site (shes on this site daily for work). I asked her about it. She said 'it was a stupid brief moment of curiosity while she was on that site if he found another job yet'. She learned a few weeks back (her sister ran into OM)that he recently lost his job.

I told her how frustrated I was to see this on our computer. She said she felt stupid for doing it, that it just crossed her mind while she was on this site to check if he found a new job. She said it meant nothing, but she completely understands why I would be upset about it. I told her it puts doubts in my head. She said she was frustrated with herself as shes been trying her hardest to regain my trust and be transparent. I told her I spend a lot of time trying to get this guy out of my head and something like this triggers all the thoughts over again. She said she understood. She assured me that they haven't had any contact and that she would never contact him again as she promised a few weeks ago. She also said that if he happened to try to contact her that she would tell me. I told her I again would take her for her word and move pass this. I was clear that I never want her to do any searches for him and I never want to talk about him again unless I bring it up. She understood and agreed.

What should I think about this? Everything has been going great otherwise. She asks me numerous times daily if I need anything and if there's anything she could be doing. She came to me this morning asking if there was more I wanted to talk about from our convo on the weekend. Shes been very loving and affectionate and our sex life is getting back to normal. We're very open and honest and seem to be communicating well. We're going away this weekend on a weeks vacation with our kids and W family.

Should I just accept this as a small lack in judgement on my W's part and move on? That's what I've done but I'm curious on your opinions.
