Scenario: In a relationship with someone for over a year. Known him since high school, fully trusted him. One day out of the blue he vanishes and doesn't respond. Around 12 weeks later after no responses and a lot of worry, bits of info start appearing that he's moved into another woman's house. It turns out to be true (2 streets away!). To this day he has never actually admitted it or apologised. He also owes money (£900). I have never bumped into him to have it out with him, he deleted all social media, changed his number and the one person who has seen him that knows us both he couldn't get away quick enough.
I've told 8 family members/friends, 7 told tell me not to drop it, 1 has said to drop it. WWYD? I don't want to drop it personally but at a brick wall of how to sort it.
AIBU = You'd let it all go
AIBU = You wouldn't let it go and would keep trying to find a way to get your money back, call him out or both (how?)
