Navigating a New Relationship After Trauma: How to Heal and Love Again

How do I navigate a new relationship after a traumatic event? I've been talking to a guy for about a month, and we really like each other. Honestly, things are going so well and it feels really healthy. However, about a week ago, I was SA'd by a different guy. The guy I like has been really supportive, but now I feel so broken. I told him it's not fair that we've only known each other a month and that he cares about me so much and I'm unable to reciprocate right now; it's not fair that I'm already sort of broken. He keeps telling me that he doesn't mind taking care of me right now, that he knows I would do the same in a heartbeat if the situation was reversed, that he knows I would show affection if I had the energy, and that that's all he needs because he wants me to focus on getting better and not on what's "fair" to him because he's around because he wants to be because he cares about me. I just feel so bad because we're not even officially bf/gf yet, this relationship is still so new, and he's already seeing the worst side of me. The fact he still loves me is incredible and I'm grateful, so how do I get over the feeling I'm too broken to be loved? How do I continue to move forward with this relationship, or at least stop being afraid to be loved and show love? Most advice I see for navigating relationships after being SA'd is either when the victim has had a few years to heal or when the victim has already been in a long term relationship. Idk how to navigate it when I'm already in a fresh relationship.
