<human>: Give me the gist of the text in a nutshell

My boyfriend and I have been dating since February. It's been a tumultuous relationship to say the least, with him having made some questionable decisions regarding other women early in the relationship. However, I decided to forgive him and move on, and things have been pretty great since we worked out our issues.

Though I am able to forgive his mistakes, I still find it incredibly hard to trust him, and he doesn't really make things easier. I don't believe he's cheating on me, but he just acts really shady sometimes.

Here's the issue: we're about to be separated for the better part of 3 months for our college summer break. We'll be on opposite sides of the country, and currently don't have plans to visit each other. I am incredibly worried about how my trust issues are going to affect our relationship while we're apart. If I can't trust what he says he's doing when he's a mile away, I know I'm going to drive myself crazy this whole summer.

I am strongly considering asking him to take a break in the relationship while we're separated- less consistent contact, allowed to see other people, etc. My logic is that if we're not officially "together", I know that I won't get as upset as I do now regarding what he does. 

My questions: does this seem logical? I feel like a break would give me time to level myself out, clear my head etc, but I don't want him to take this as me breaking up with him, because i'd love to pick back up in the fall. Should I go through with this? What would be the smoothest way to propose this idea?
