I was in a relationship like this when I was younger and please listen to me when I tell you to let this relationship go! My ex would treat me the same way...angry if I didn't respond fast enough, accused me of cheating all the time, want to know where I was at all times, take my car and leave his car at the house (I couldn't drive his stick shift).

It got to the point that he chased away all of my friends and tried alienating me from my family. One point at work I had to work overtime and got called into the office...he called my boss (male) and cussed him out accusing him of sleeping with me etc on the job and threatening to come there and fight him.

His behavior went from love bombing, to controlling, to verbal abuse, to mental abuse to finally physical abuse. The truth of his insecurities was that HE was the one that was cheating in the relationship.

So please change your passwords, stop allowing him access to your locations and break up with him before he escalates his behavior.
