I was in a messed up relationship which ended 3 years ago, I loved him a lot amd I still do even though he left me for someone else in the worst way possible and we are still in contact cause we share the same friends and whenever we meet he gets a little bit physical and I don't stop him even though he is with someone else and he had hurt me so much in the past. so my parents are going to be out of time for a while and I can't stop thinking about inviting him over even though it's completely wrong cause he is with someone else and also because he has caused me so much pain and betrayal but I still want to see him and be with him idk what I should do, I have an exam tomorrow and I can't stop thinking about him
