This sounds like a soap plot but I guess real life gets messy too. First question, do both brothers know about each other? Because if you’re secretly seeing both of them, that’s not being torn, that’s cheating on both of them. And they’re going to find out eventually because brothers talk.
If they both know and they’re both okay with it, that’s still a recipe for disaster because family dynamics are complicated. What happens when one of them gets hurt? What happens at family gatherings? What happens if you pick one and the other can’t handle it? You’re not just potentially losing a relationship, you’re potentially tearing apart a family.
You need to step back and really think about why you can’t choose. Is it because you genuinely like them both equally, or is it because neither one is quite right for you and you’re trying to split the difference? Sometimes when you can’t decide between two people, the answer is actually neither of them.
Make a decision and stick with it. Or better yet, take a break from both of them until you can think clearly. Being in the middle of this triangle is probably clouding your judgment. You deserve someone you don’t have to be torn about. And those brothers deserve someone who’s sure about them.
