What am I feeling?

I've been with my girlfriend for over a year now, and we’re both 19. Our relationship has been really positive, but I’ve found myself reflecting on my experiences with her in a way I never have before. Caring for her deeply has led me to self-analyze and identify areas where I can grow. In the past, I've done well in certain respects—like validating her feelings, really listening to her, and setting aside my pride. However, I know I’ve struggled with showing empathy and have occasionally let my jealousy and anger get the best of me. Recently, I've been motivated to improve our relationship even more. I've noticed that we don't argue anymore, which she attributes to my efforts to address my shortcomings. However, I sense that she might be holding back from sharing her feelings fully because she worries that I won’t understand her. I recognize where she's coming from, and I'll be there for her until she feels comfortable opening up again without fear of being invalidated. Being in this relationship has also illuminated my own flaws. I’ve realized that I can be envious and quick to anger, which isn’t the best way to behave. But she inspires me to be a better person—not just for her, but for myself and everyone around me. She encourages me to let go of past hurts, live in the present, and embrace positivity. In fact, she even motivates me to explore a relationship with Jesus and attend church, all in the pursuit of becoming a better man. I want nothing more than to share my life with her. I know we’re young, but this relationship feels like home to me. I can cry in her arms without feeling ashamed—she was the first person I ever cried in front of, and she makes me feel safe. Lately, I’ve found myself overthinking whether this is love, and I’m not entirely sure why. All the signs point to love when I’m not overanalyzing, but when I do, I start to feel like I’m holding her back from reaching her full potential. The Bible says that love is not envious or hateful, that it prioritizes the other person, and I know these are qualities I don’t yet fully possess. I’m committed to learning and growing, even considering therapy if that’s what it takes to be the partner she deserves. This is all so confusing because I genuinely care for her and have strong feelings, yet I find myself questioning our love. It feels like I’m being tested to see if what we share is real. But if I have the ability to love her in the way she needs, I’m willing to do whatever it takes because I want her, and I cherish everything that comes with being with her. My heart aches while writing all of this.
