question....

me and my boyfriend spent the night at my grandparents house last night (family thing) he woke up at 2pm left with my Car only to go to our house 30 minutes away and been gone for 7 hours I can't get in touch with him I told him to bring my car home hours ago. I'm seriously thinking about calling my car in stolen.... am I just being stupid. FYI we've been rocky for a while now. I don't know where he is who's he's with or what. honestly I just want my car back. I can't trust him. also he hasn't called all day to check on our daughter who is 2.
