I’ve been with my partner for a few years now but it is definitely a complicated relationship. Recently things have went downhill and I caught another guy messaging her trying to meet up. I don’t know if they actually did meet up or not but she says they never. She seems to have lost interest in me although when I ask if she’s gone off me, she says that’s not the case. I just can’t work her out. Can anyone see if she has been cheating or if she has feelings for another guy? I’m hoping for guidance saying to either walk away from the relationship or words of hope towards the relationship…
