My boyfriend loves his ex

Unknown asked 3 weeks ago

We’re all out at a warehouse (no idea) she goes outside because she’s upset im a nice person so I go to see if she’s okay when I ask her she says no but shes not going to tell me because she hates the fact hes happy with someone else I go back and tell him and he says we need to talk I look at him and ask if he still loves her and he says yes and that he’s not happy with me and wants to be with her but in real life we’re really happy together we never argue and I’ve asked him if he’s happy and he smiles and says yes why wouldn’t i be? So why do I keep dreaming about him running back to her?
