Am I overreacting for feeling like my best friend doesn’t want me to date anyone?

I’m a gay teenager living in a relatively small town, and my dating pool is honestly tiny. That’s important context because the situation I’m dealing with feels a lot more complicated than it probably would in a bigger city.
A few years ago, my best friend “Angela” (15F) dated a guy I’ll call Aaron when they were around 13. Aaron later came out as gay. Their relationship wasn’t exactly perfect, but they ended on relatively decent terms.
Aaron could be a bit strange sometimes. For example, he once gave Angela a printed poem he found on Google and claimed he wrote it himself. Stuff like that. After they broke up, he blocked Angela for a long time, and they didn’t really talk.
Recently, both of our schools happened to be on trips to Rome at the exact same time. Aaron noticed the coincidence, unblocked Angela, and they had a friendly conversation about it. Since then, Angela has been talking about how much she’d love to reconnect with him as friends.
The thing is, she genuinely thinks very highly of him. She constantly says he was always there for her, helped her through difficult times, listened to her problems, and was generally a really caring person. She even used to joke that she’d love to see me date him.
I always rejected that idea because Aaron simply wasn’t my type, and honestly, dating a friend’s ex felt weird.
But lately I’ve been thinking about it more. Physically, he still isn’t really my type. However, when I stop focusing on that and look at his personality, he actually seems like a pretty good catch. The more Angela talks about him, the more I realize he sounds like someone I’d probably get along with.
Here’s where things get complicated.
My other best friend, “Elvis” (17M), is also gay and actually dated Aaron too.
To be fair, Elvis admits that he wasn’t exactly a great boyfriend in that relationship. He was getting to know two people at the same time and the relationship ended badly.
Ever since then, Elvis has been extremely clear that he does not want me interacting with Aaron at all. Not dating him, not talking to him, nothing.
The problem is that Elvis also has a long history of reacting this way whenever I’m interested in someone.
He’s incredibly flirtatious with me. To this day I genuinely can’t tell whether he’s joking or not half the time.
He constantly tells me about his crushes, but whenever I mention mine, he immediately starts criticizing them. It doesn’t even matter if he knows the person. He’ll say things like “they’re not worth it” despite having zero information about them.
He also jokes that he’ll never introduce me to any of his friends because he wants to “gatekeep” them from me. The weird thing is that while he says it as a joke, he actually follows through. He genuinely seems uncomfortable with the idea of me dating anyone.
Maybe part of that comes from the fact that I can be a bit intense when I develop feelings for someone. I don’t know.
The thing is, Elvis is genuinely one of the best friends I’ve ever had. I love him dearly, and no potential relationship is worth losing that friendship.
But at the same time, I feel stuck.
A few days ago, Aaron replied to one of my Instagram stories and asked where a church I’d posted was located. We follow each other because we have mutual friends.
When I told Elvis, he immediately said, “I guarantee he doesn’t care about the church. He just wants an excuse to talk to you.”
I replied politely and gave Aaron the location.
Aaron hasn’t messaged me since.
Yet somehow Elvis is still annoyed that I responded at all.
Meanwhile, Angela couldn’t care less. She keeps telling me that she just wants to reconnect with Aaron as friends and that she wouldn’t be bothered if anything happened between us.
So now I’m confused.
Part of me thinks Elvis should understand my position. Being gay in a small town means opportunities to meet compatible people are rare. Really rare.
Part of me wonders whether Elvis is being protective, possessive, jealous, or if this is all just a joke that’s gone too far.
What makes it even more complicated is that Elvis has some kind of history with a huge percentage of the gay guys in our area. If I completely ruled out anyone who had ever dated, talked to, or been involved with him, I’d probably be eliminating most of the available dating pool.
I don’t even know if Aaron is interested in me. Maybe he isn’t.
But I do know that I find it strange that my best friend seems upset whenever there’s even a possibility of me connecting with someone.
Am I reading too much into this? Is Elvis being unreasonable? Should I avoid Aaron entirely because he’s my friend’s ex, or am I overthinking a situation that hasn’t even become romantic yet?
