Cis woman wants to help her trans man partner with gender affirmation

I (20,cisF) and my partner (23, transM) have been together in long distance for over a year now. We love eachother deeply, and want to support eachother emotionally. We share everything that crosses our minds and we don’t feel the need to hide anything about eachother because we know we won’t judge eachother for anything, even the most embarrassing things. We are together and here for one another no matter how bad things get.

Despite that, my partner is still feeling down very often, due to being stuck in an incredibly unsupportive family, forced to be in the closet constantly because of that and the fact that he lives in a red state. He intends to leave for good one day and reunite with me in my country, which I will not disclose for safety reasons. That takes a toll on his psyche, that as well as very negative past experiences relating to friends he had. He has moments in which his dysphoria gets especially horrible, makes him think he’s not a real man, constantly comparing to cis men, and I try my best to affirm the opposite and that I genuinely don’t care what his body looks like, and that I will support him on achieving his transition goals once he’s with me and when I’ll be able to materially help him improve that.

In the meantime, those dysphoria moments are horrid for him. I try my best to reassure him that his appearance, especially an appearance he doesn’t want to keep, doesn’t reflect the truth that he’s a man, but sometimes, it’s simply not enough. He can’t do anything right now, because as I said, his life situation forces him to be closeted completely irl. I just. Don’t know what to do. I want to help the love of my life the best I can, I just want it to stop in the meantime he manages to reunite with me. I am completely helpless and lost. Please help me, thank you for reading me and replying if you can…
