So every so often I get really strong intrusive thoughts about my DP, I then question if he loves me, if he’s faithful, is he’s lying to me. This is every couple of months and lasts for about 2 weeks and then it subsides. I don’t quite understand it, he’s never given me reason to think or feel like this. I’m 38 for context. Has anyone else every had this before? Is it some kind of mental health, hormones or some weird gut instinct?
