<human>: Provide a brief overview of the text.

My boyfriend had trust issues from the start but they went away for a while after couples therapy. Over the past month it's come back even worse. 

I'm a server and he hates my job because he thinks I'm cheating on him at work. If my phone gets a text message he always ask who it is or wants to see it. If I'm kept late at work, he gets mad and thinks I'm cheating. If I'm early to anything he thinks I was lying about where I was or lying about where I am going. If he catches me looking in any direction longer than a few seconds, he thinks I'm staring a guy. Long story short, He spends all his time and energy on trying to catch me cheating on him.

I have never cheated on any boyfriend. I've never lied to him. I've never even had anything that could remotely look like cheating on my phone, Facebook, or anything. I've worked harder in this relationship than any other and I'm very proud about how honest and upfront I've been to him. But he can't see it.

I've done therapy, GPS tracking on my phone, Open door access to my phone/laptop/facebook/ect, Not going out with friends when he couldn't go. I don't know what else to try to get him to trust me.

He withholds the trust I need in this relationship but gets mad that we don't have sex that much anymore because I don't feel like he loves or trust me. 

What can I say or do to either show him how irrational he is acting or make him trust me?
