[u/Legitimate_Olive4333]

So my girlfriend who I’ve been with a decent amount of time has begun to show psychosis and bipolar tendencies. It’s severe she has conversations with someone who ain’t there like full blown convoys. She’s constantly getting angry and tries to get violent. She cleans my apartment time after time even if it has already been cleaned. She is begging to get violent with me threatening to stab me. PLEASE HELP!!!!!
