SUBREDDIT: r/relationships
TITLE: Me [33 F] with my ex [35M] together 3 years, broken up 2 mos. I have realized that our breakup was not mutual, I want to get back together for the long haul. Is there any benefit to taking infidelity to my grave? He cheated too.
POST: Martin and I were together for 3 years, living together for 2. We broke up 2 months ago because we were drifting apart, largely due to the following timeline:

* We lived together for a year before he cheated on me once, while drunk

* I never really processed the infidelity or got mad about it, we moved forward

* I started to distance myself, lost interest in sex with him, didn't like being touched

* I regained an attraction to an ex-boyfriend, started cheating with him

* Preparing to go to grad school became my #1 priority and I really withdrew from the relationship 

* We decided we weren't meant to be together and broke up mutually

It's been 2 months now. I am finally able to move my stuff out of our place in a couple of weeks and am dreading it. I regret breaking up and truly believe that we belong together for a number of reasons I won't go into here for the sake of anonymity (he is a redditor).

In the event that he agrees with me and takes me back, is there any benefit to keeping my own infidelity a secret for the rest of time? If the unanimous agreement is that I should be honest about this, what are good ways to discuss it while minimizing the damage?

Please help. Thank you.
TL;DR: 
Mutual breakup, mutual infidelity. I want to get back together but, if we do, don't know if or how I should discuss my behavior.
