Never thought my ex could turn out to be abusive/toxic?

She's forcing circumstances around me in a way that i should give up on people who are close to me (friends) be it new or old so that she can have their complete attention from them or she developed unhealthy attachment towards men, weird part is, she's married to someone else already and a mother of 4 kids, i seriously don't understand her problem, apart from being with her husband she's sleeping with my ex-coworker and is chasing my friends/aquaintances or anyone who's close to me, when i retaliate for her antics, she sneaks into my workplace and influences the management of my company it treat me like shit or asks them to make a demeaning remarks on me for no reason about my work, that bitch made my staff hold my this month's payment 😡, she's not letting other women/girls to talk to me either, forcing me to get married to someone I don't even know and I am not even mentally ready for a commitment or marriage, seriously i don't know what to do of this crazy psychotic lady. My feelings and affection for her is long gone. IDC for her but her meddeling in my life is getting on to me and she starts name calling and blaming etc.
