My husband was briefly sending (seemingly innocent) messages to a much younger woman behind my back. He admitted to me that he had met her while away alone, but not about the messages. He said he didn't occur to him it was problematic, and he only saw it as friendship, but that he was attracted to her. I have to trust him that nothing happened between them to move forward. He claims the messages were due to checking she got home safe and a shared hobby. I have probably been stupid, but I contacted her to clarify - no reply yet.
Can anyone give me any advice for moving past this? It feels like I may have caught something before it may have ended up escalating. So I would prefer not to end a very long term relationship over this. But equally, it feels a bit like things will never be quite the same again at this point. I'm heartbroken. I'd really appreciate any thoughts from anyone who has been in a similar position and been able to move past it, at least on some level.
Thanks in advance
