Today I went on my boyfriend’s phone (in front of him) and deleted his ‘ex-partner’ on snapchat. He knows I have felt extremely insecure about her for a long time to the point where I’ve been been continuously looking up her Facebook on my phone. She is his “best friend” and him and her use to have sex on a regular basis until him and I started talking. We broke up once when we first started dating and he ran to her along with another one of his ex girlfriends. We’ve been together for 8 months now and he still had her as a friend on snap, Facebook and still has her phone number. He swore they don’t talk but got extremely angry and defensive when I deleted her... I don’t see how it should be an issue is he “wasn’t talking to her” and he knows it’ll make me more comfortable in our relationship.
