My wife (27) told me she gave another guy a blowjob but nothing more happened [m]

Been with my wife for 9 years but she recently confessed to me she gave an older guy (she thinks he was in his 50’s) a blowjob in his car after her shift at the pub she works at.
Apparently he offered her a lift home rather than her having to pay for a taxi and as he was a regular she talks to she didn’t think anything of it. anyway she somehow ended up giving him a bj in the front of his car. After confessing to me I was mad with her and we didn’t talk for a while but after calming down whenever I think about her sucking his cock I get hard as a rock but also a bit jealous at same time.
