So to try and cut a long story short in December I walked into my living room and a friend of mine jumped away from my SO as if they were doing something they didn't want me to see. They both swear nothing happened but I just can't get the image out of my head and I believe if anything did happen it was her attempting to kiss him as I have always had that vibe from her. I haven't spoken to her since and she has kept out of my way (we work together). Now my SO works in the same place but on the night shift but as of next week will be working on the day shift on the desk next to hers (I'm on a different department) .... I know I just need to let it go and trust that nothing will happen but a part of me hates the fact he will be working so closely with her. I have attempted to talk to him about it but he doesn't understand why I don't trust him. so I guess my question is how do I get that image out of my head and let it go?
