The things these people do to us....It makes me crazy. I would agree with everyone on here and contact a DV center about this. Not to freak you out, but the fact that he is taking your phone, disconnecting the battery on your car, drinking on probation are all warning signs of abusive behavior (feeling he is above the law and feeling he has the right to control where/when you leave). Just something to consider. They can be really helpful when starting to navigate this kind of thing. Hugs to you in all of this.
Mine would block my car in the driveway with his, take my debit card, etc. Grr...
