<human>: My boyfriend decided today that we would be going on a break.

This is because of him discovering through means of my ex telling one of my boyfriend's best mates that when I had met said boyfriend, I wasn't actually single, I was still in a relationship. We have been going out for about a month and a half now.

I met my boyfriend on a University camp, far out of phone reception, and was planning on breaking up with my now ex boyfriend once returning from this camp, and did so the night I got back. He wasn't expecting it, as I had kept my concerns to myself for a while, and so it was quite unplesant. 

My boyfriend is now concerned that one day I'll turn around and do the same thing to him, and break up with him seemingly out of the blue. I've told him numerous times how I feel for him, and how quickly I've come love him. 

I want to give him all the space he needs to decide what he thinks, but our lives are fairly involved as we do the identical uni course, and are good friends still, I'm really not sure how to go about this without him thinking I've a. Given up or b. Can't leave him alone.

Can you give me the gist of the text in a nutshell?
<bot>: I made the stupid choice not to tell my boyfriend the truth from the start of our relationship on my own terms, and am now on a break and wondering where to go from here
