Hi everyone, very long story short I am in the weirdest situation of my life. I've been with my DH for 14 years, we had a baby 8 months ago. We went to a birthday party at the end of Nov, and we both at the same time met a woman there. We did not know her before this. She then added my DH on snapchat the next day, and there had been some conversation. A few weeks later this woman had told all of our friends that her and my DH had been having a passionate affair while my husband was meant to be at work (my husband is an outdoor worker and works with people all the time). My friends obviously told me, I questioned my DH on this as I was clearly very upset to hear this, and I also questioned this woman. She gaslighted me saying she had never said such a thing, and treated me like I was crazy for asking denying she ever said anything and just said shes having a hard time at the moment, and DH stayed very calm and supportive and was willing to assist in any investigations I was doing, as far as him messaging her husband telling him what his wife has been saying and also letting me go through everything on his phone (yes she is also married) DH story has not changed throughout me questioning him, he also doesn't appear guilty. I downloaded his snapchat data, to further investigate, there was nothing incriminating there, he is also never out the house unless he is working, the rest of the time we're raising our child, very happily. At the time he was allegedly having this affair, he was obviously at work, but behaviour wise, everything was great! Literally no different to normal.
I'm just so confused of why someone would say something like this?? Make it make sense! It's literally destroying me.
