How do I save my 6 year long relationship? Please help?

We've been friends since we were 10, starting dating at 15, and are currently 21. When we were 10, we met in school, after which I moved away. 15, we got together, and have been in an LDR ever since. In 2019, he set off for uni, in a country that is across the globe, we have a ten hour time difference. we have managed to stay together this whole time in an LDR. We want to marry each other. But in such a long relationship, there were hurdles, and now we're in a tough spot and I need advice.
I come from a very abusive household. I have had issues all my life, including mental health, and then getting abused on top of that. Ever since he began dating me, he became my sole source of comfort. I had no support system, no friends, could not afford therapy. I built a support system this year, in uni. I made good friends and finally began therapy. And this is the year I finally saw progress. I am getting better now.
But because he has spent nearly 5 years of his life, as a young teenager, acting as my therapist, he lost himself. He could not build his own identity because he was always so invested in my life. Currently, we have taken a break because even though I, and the relationship got better, he's being hit with an identity crisis and doesn't know what he wants out of life. The most unfortunate thing is, neither of us is to blame here, I genuinely had no one to help me through my anxiety attacks, and we were young and didn't understand how important boundaries would be. our relationship has become a trigger for his anxiety because he never got to live his life properly. He wants to spend some months apart, and then give us another chance to see how it feels, and im terrified he won't want me anymore. I feel like I'm going to lose him for good, and it's neither our faults. My only hope is he gives us a chance, with an open heart, after he has recovered. I have no doubt that he loves me, we were going to tell our parents about wanting to get married next year.
