How much are you prepared to overlook for the sake of love?

Hey everyone! I'm a 19-year-old female, and I've been in a relationship with my boyfriend, who's also 19, for over a year now. We met when we were both 17 and started dating when he was 17 and I was 18. A bit of background: I didn’t have healthy relationship role models growing up, just what I saw in movies and on TV. Because of this, I never really understood what a healthy relationship should look like—just the idealized version in my mind. I often turn to AI for advice on relationships, which is kind of funny. As an only child, I grew up pretty independent. My boyfriend, on the other hand, has had a mother and stepfather for most of his life, but there’s a noticeable emotional distance in his family dynamic. From what he's shared about his past, it seems there isn't much emotional closeness among them. Now, regarding our relationship: we've had our fair share of arguments and have had to make positive changes. We've both learned a lot and experienced some unhealthy phases, too. This is both of our first serious relationships. While I've dated a bit, it's never lasted due to my commitment issues, and he hasn't dated much either because he was homeschooled and primarily interested in flirting with girls online. Every challenge we face brings us closer together, and I'm proud to see our growth. He has a lot to learn about emotional intimacy since he was diagnosed with autism at a young age, and I sometimes feel like his parents didn’t provide enough support. This has resulted in me doing most of the emotional labor because he’s more emotionally immature than I am. Despite the challenges, he’s dedicated to me and is committed to improving, just as I am. Right now, things are going pretty well. So, here’s my question, and my TL;DR: If you're young and a bit immature—perhaps making mistakes—but very committed to the person you love, how much would you be willing to forgive? I'm looking for a general perspective since I’ve never modeled a healthy relationship, but I want to build one of my own. I know we're both young and bound to slip up—what’s a reasonable amount of forgiveness to expect in the name of true love? What constitutes a healthy and constructive approach?
