You two are stuck in a feedback loop. It’s a really tough spot to be in until you realize it and work on it.
Anxiety in a hostile environment (or the perception of being in a hostile environment) will be met with reciprocal hostility. And then things escalate, and then repressed, and it continues. You two are fanning each others flames. You may be more alike than you realize or care to admit.
Good luck finding a therapist. Remember it’s a lot like dating…you may get lucky on the first meeting, you might find yourself completely incompatible with them, or you may find someone that you’re comfortable enough with to build a good rapport with over multiple sessions.
Proxies aren’t bad they are just dated.
Ironically the big problem with proxies is really that software doesn’t support them properly, usually due to lazy or unknowing devs.
