19M- 20F (LDR advice)

My French girlfriend (20F) and I(Indian-19M) have been together for 1.5 years. We were together in university for 2 years in France. Now we have had to part our ways since we have a unique degree arrangement. I will be in California for 2 years and she will be in Taiwan for a year. She is mostly sure she wants to apply for Masters in France and I want to continue studying in the UK (first choice) or the US (second choice). Nevertheless its hard for us to meet even twice a year (summer and winter break) due to financial and visa troubles. Its doable but hard. We don't know how the LDR will end, we are both career ambitious- and are futures are as unpredictable as they can get.

Some facts

1. ⁠We are both each others first loves. She likes the idea of experimenting with other people, I don't know how comfortable i am with that.
2. ⁠I am having these doubts after a month of LDR. We have been barely talking since we are both busy in our stuff rn. But, last night I was not mentally okay and needed support. I know she was outside with her friends so I dropped her a text when I really couldn't handle it anymore. When she texted I had finally calmed down and gotten some sleep. Today morning I needed some form of connection so I texted her how she was, etc...she texted me saying she needs some space and will text me. We have talked about this before. She gets mad at me when I don't text her back and she needs connection, but when I am breaking apart and genuinely need a bare minimum connection, she just texts me saying she needs space. I want to respect her space, but I feel like my needs should also be seen as important when I am struggling and need help- especially when the same is expected off me. And we have talked about this before (not in the context of this LDR scenario- but more generally). I don't know if this is sustainable.

In this context, I genuinely don't know what to do. I love her, but I don't know if its this context or something else but I don't feel like this sustainable. I want her to be happy, even if that means losing her. But she says she wants to atleast stay friends if not partners. Idk if its stupid socialisation or patriarchy or third world conditioning, but i don't think i can do that.

If anyone has any advice/resource that can help me navigate this I would be insanely grateful.
