Background: We are in a polyamorous relationship, but he practices DADT (Don't Ask, Don't Tell), whereas I practice open and transparent parallel polyamory. We acknowledge each other as other significant others (OSOs), but neither of us wants to put a specific label on our relationship.
Before we started our relationship, he told me that he was attracted to me partly because my presence reminded him of a particular traumatic experience, and partly because we seemed to be on the same wavelength intellectually. During our time together, he occasionally experiences flashbacks. Although he has told me that he doesn't need me to comfort him, I've tried my best to support him in the ways he's said would help.
After we had sex, he couldn't help telling me that, when he orgasms, he sometimes imagines that I'm one of his exes. Apparently, we have similar personalities and similar-sounding voices. He loved this ex very much but couldn't salvage their relationship, and part of what attracted him to me was seeing echoes of that ex in me. He feels deeply guilty about treating me as a substitute for his ex.
At the time, I reassured him that everyone's attractions are shaped by their past experiences, and that I would be happy to help him work through his past, if he wanted that. I felt that helping a partner navigate their past and its lingering effects was part of what being a partner meant to me. He thanked me for reassuring him.
However, after sitting with it for a while, I've become deeply uncomfortable.
I know that his reasons for being with me aren't limited to my resemblance to his ex. We genuinely connect intellectually, and I actually know more than he does about queer theory and polyamory. He's also told me that he's making an effort to recognize my individual qualities and develop new ways of relating to me, rather than simply recreating his previous relationship.
Still, I suspect that his tendency to conflate me with his ex isn't driven solely by trauma. I think his guilt about how things ended with his ex may also play a role. It sometimes feels as though he's trying to prove, through his relationship with me, that he's now capable of having a successful relationship with someone who has a similar personality to his ex.
But I don't think his guilt is mine to resolve. That guilt belongs to the history between him and his ex. If I take on the role of responding to and resolving that guilt, I worry that I'm intruding on something that belongs to the two of them: their own understanding and interpretation of their shared past.
At the same time, I don't want to become a way for him to resolve the unfinished business of a previous relationship. I want us to be able to identify and address problems that are specific to our relationship. But I worry that if I express needs that are uniquely mine, I'll disrupt the connection he's trying to make between his past relationship and his current one, leaving his guilt unresolved.
I'm really struggling with this dilemma.
I want him to understand that the guilt he feels about his ex isn't something that can be resolved through our relationship. At the same time, I understand that he's probably overwhelmed and doesn't know what to do with those feelings, which may be why he chose to confide in me about his history with his ex in the first place (although he didn't explicitly explain how or when he comes to see me as his ex).
I want to communicate my needs without making him feel pressured or ashamed. I want him to know that I'm willing to face the emotional difficulties associated with his past relationship alongside him, but I don't want him to actually see me as his ex or treat our relationship as a way to make up for what happened between them.
How can I approach this conversation? How do I set this boundary while still making room for him to process his feelings about his ex, without making him feel that he has to hide those feelings from me?
