To be honest, I've been the manipulative one in the past. I don't know if it counts for anything, but I was really not in my right mind at the time (depression, anxiety). I was always trying to get better, but sometimes you fuck up and relationships suffer as a result. I do wonder sometimes how my relationship with my ex would've differed if I was more like I am now. I think we probably would not have even dated (he was perfectly respectful and everything, but not really interested in commitment). I don't regret those experiences. I'm sure my relationship with Boyfriend would not be as it is now without having made all those mistakes, so I'm grateful.
Boyfriend identified some of my behavior as passive aggressive early on. I've gotten better. He's gotten better. Sometimes, we're not clear about how we're feeling and assume the other knows things without being told. Our arguments usually end light-hearted, with both of us saying, "Wait, this again? Okay, what did we not communicate to each other that ended up with us getting ridiculously pissed off?"
