About to do something really bad.
After 8 years in a relationship my boyfriend now ex-boyfriend. Has a new girlfriend he found while he was on a break with me. Lately he’s been calling me and we’ve been hanging out but the girl is still his official girlfriend. At this point I’m dumb for entertaining him and he’s an asshole for trying to play with both of us. However I am tempted to tell her what’s been going on? I know it’s malicious but I’m angry! Should I ?
