Input: Me and my ex boyfriend have been broken up for around a year, I have recently become single again and messaged him. He advised he had a new girlfriend and he was happy, however I invited him round and he accepted the offer. Whilst he was at my house we kissed, the next day I saw he uploaded a photo of him and his girlfriend kissing and I commented on the photo saying ‘bit cringe considering you were kissing me yesterday’. Am I the arsehole?
