Found out a few weeks back my partner has been lying to me for months. Had a falling out with my bestie three months ago and they’ve been communicating behind my back. Few things came up that caught him out and he blatantly lied. She came to me wanting to sort things out and after dinner and a few wines told me. I just don’t know how to move on. Not talking to the friend anymore and partner wants me to ‘get over it’
