Hello Trix:
This "failure" is not on you. It's on him. Divorcing him is not a failure!
Eventually, hope you'll recognize that divorcing him was one of the smartest, best things you ever did for yourself.
Agree with BTB. Yes, once he's out of your life and you've taken the time to process the marriage, I too bet you'll recognize he's always been a jerk. You were like the proverbial frog slowly boiled in the proverbial pot of hot water - you grew accustomed to his poor treatment. Now you're recognizing the real him and it isn't pretty. Which is why I'm chiming in. Don't usually post in this forum 'cause I've never been divorced. Yeah, some of his behaviors are "normal." But the stalking is NOT normal.
Frankly, I'm concerned about him stalking you! Don't minimize this. Please do whatever you need to do to block him from the ability to track the car or access the CCTV. Can he track your phone too? Change the passwords, get your own cctv account, get a new phone, sell the car, - whatever it takes. Please talk to your lawyer about changing the locks and the pros and cons of getting a restraining order while in the midst of a divorce. Don't want to poke the bear, but you must protect yourself. Your safety must come first! An angry STBX is bad enough. An angry STALKER STBX seems dangerous. Be safe.
ETA:
Go no contact as much as possible. Kids and finances only. "Talk to my lawyer about that" is a response that will help protect yourself. No contact means no new hurts. You're divorcing him so no more chit chat about his relationship with OW, how horrible you are and how dare you date, etc. He's being emotionally abusive! Sounds like channelling all kid communications (except emergencies) through a family planning app would be a good idea, and something to include in D agreements. And dating before the D is final.......dunno. He's a vindictive ass. Is this something he could use against you regarding child custody, etc. Suggest talking to your lawyer about that, too.
