Bit of background... DP cheated on me 2 years ago, I've posted about him before and got some great advice. We made it though his cheating, however I regret doing the "pick me dance" and it took me more than a year to get over the betrayal and pain.
Over the last 2 weeks I've been having the same sinking feeling I had when I first became suspicious he was cheating. His behaviour flips from being super nice and caring to snappy and distant. He has been a bit cagey with his phone too, minimising the screen if he is texting etc. He just doesn't seem the same and I feel sick and on edge. I don't know his passcode so I can't check his texts, it's been on my mind constantly and I'm even dreaming about it!
I've asked him if there's anything wrong etc and he said no.
I don't really know why I'm posting, I can't sleep as my mind is in overdrive.
