Most Helpful Guy
If there's trust issues its not good sign. Normally when a guy has trust issues its because he's fooling around and trying to cover it up. Im not saying he is it just sounds a bit dodgy to me. Give him space, call him and maybe set up a coffee and talk about it. Present your issues and your thoughts and work from there

Sounds like he's cheating. He's controlling? you must ask yourself why would you want someone to control you. Perhaps you should take this time to evaluate you. If you could careless about someone controlling you... Don't worry he will come back unless he found someone better than you most controlling people come back to the people that allow them to control them.
