Bro, I don't know what might be going on with your girl but, it sounds like she 's just looking to start some drama by going through your shit while your gone. I mean sometimes people try and accuse you of shit that they might be doing just to try and justify what they might be doing behind your back. You've been together for three years now so you pretty much know each other and what makes one another tick. So if your trying to fix things and she continues to push bull shit drama then the shits not gonna work. Ya'll need to sit down and talk this shit through and figure out if this relationships worth fixing for yalls sake and your sons. Good luck bro hope I don't see ya on Dr. Phil!
