I met this girl at the end of 2020 and we connected really well, had an undeniable chemistry. Attractive, fit, about 5'5", fun to be around.

First Break
Unfortunately around March of 2021 she broke off things with me after we had an argument over a gift I gave her. I planned out a date, picked out a dress for her. She was dealing with trauma based on her past (she has been with 6 guys as I found out). I really liked the girl though and was pretty hurt when that happened.

Reconnected Again
Around August time she reached to me again saying that it was stupid of her to leave me and that she wants to reconnect. I couldn't really help it, again I liked the girl. She did tell me the truth (almost) that she did date a guy for 2 months in that time frame. She did not tell me that she also had a miscarriage from that guy, till much later.
Anyway, we reconnect and decide to start dating again. In that time frame I bought a house and also was getting ready to leave for military (reserves) in the fall, so we only had a couple of months together before I left.
We talked a lot while I was out in training, texting and calling each other often and when I got back in the summer of 2022 things seemed to progress well, not without small hiccups, but I though she really liked me and despite the difficult past I willing to look past it because I couldn't help but like the girl.
Around the fall of 2022, she started talking to me about taking a half a year trip to South East Asia. She felt stuck at her job, not sure what she wanted to do professionally etc. It was a big dream of hers to see these countries, where she would feel less out of place (she is an Asian girl). Eventually she pulled the trigger that November and planned out a trip and shared the details with me, how she would use her savings to fund it, asking for advice etc.
I was not too concerned as things were progressing in our relationship.
She moved a lot of her stuff to my house, we were talking about introducing our parents etc... It was suppose to be a bucket list item.

Departure to South East Asia
It was finally time for our last date (end of February 2023), she and I have exchanged our goodbyes, she asked me specifically to wait for her and not cheat as she would not be able to take it if I did. Of course, I said I wouldn't because I truly loved her.
Initially things were going well, we would text once a day, she and I would share photos.
About 2 weeks in, she stopped texting. I got only one text on Friday of her 3rd week that she was busy.
That seemed to be a little strange, but understandable. Another week passes by and I text her on Thursday saying that I am worried. And Friday morning I wake up to a wall of text (see link attached).

I couldn't work that Friday at all, felt like shit.
We had a WhatsApp call where she officially decided to end things. So casually and so coldly (saying I have an event soon, need to go), after telling me she loves me, just two weeks prior.
I couldn't sleep that night or in fact next two nights either. I called my friends, spent time with them watching MMA, but coming back to my empty house, realising that there is no one to wait for and no one is coming I just broke down.
Next morning I collected myself, got all of her stuff that I could fit into my car, dropped off at her relative's house and donated the rest (she told me she was okay with it over the video call).
It was really hard burning my letters that I sent her while out in training. Really hard.
I cried in public twice that day and I have never done that before.
I don't think there is coming back from that. I took her back one time, but I won't do that again.
I am posting here just hoping to hear from others, if I should do something, if I even can and if it's even worth it.
Felt a gamut of emotions, anger, sadness, hopelessness... Now I just feel lost and empty, like I am going through the motions of life, aimless.

Thank you for reading all this. If you decide to message, I can share more details/photos if you'd like. I just feel terrible and don't know what to do.
TLDR: My gf broke up with me about a week ago after a month into an overseas trip, saying she had an awakening, lost her feelings for me, even though she would tell me she loves me not so long ago.
