me and my girlfriend of 5 years have been struggling with our relationship lately, shes been acting kind of disinterested in me and denying anything wrong. i also found weird videos on her phone that seemed almost like a fantasy she was having of cheating on me with co workers? she gave me weird excuses for it saying she saved them for other reasons but i don’t buy it, it’s obvious she’s fantasizing about this, and if not, i don’t trust her. but i just love her so much and have spent all my teenage years with her. (13-19 years old) i’ve decided i need to end it as there’s no trust, i want to do it over the phone as i don’t think i’m capable of going through with it in person. how do i end this in a respectful way? how do i be okay without the only connection i have.
