My ex boyfriend and I have have sex twice since being broken up, which has been a long time (8 months). Both times, he initiated it through text and was flirty and nice but after the deed was done, he ran out the door like a bat out of hell. He didn’t stop to rest or cuddle or even talk a little bit. Just got up, got dressed and left. This past time, I said to him while he was getting dressed “wait, can I hug you?” And he awkwardly side-hugged me before walking out and he didn’t say anything. I’m slightly offended.. but mostly confused. I KNOW he doesn’t want a relationship because the only time he reaches out to me is for sex, but I just wonder... why does he always leave so quickly?
