I think my 11 year old friendship ended

I stopped wanting to hang out with one friend I’ll call him Bran for personal reasons.
My other friend I’ll call him Terry who I am really good friends with but stopped hanging out with him.
I’ve known Terry for 11 years since I was 14 I consider him a brother.

But since I stopped wanting to hang out with Bran, Terry’s stopped hanging out with me.
Me and Terry last hung out 3 months ago he said he’s sorry he hasn’t hung out he’s just been busy but I know he’s lying.
He has time to hang out with Bran. They see movies and play games together and i know they hangout too

I know he’s in an awkward position and I’m never going to ask him choose between me and Bran.
But since we hung out 3 months ago he texts me once a week if I’m lucky and it’s only a few words

And this isn’t the first time about 9 months ago I told him I was going to take a break from hanging out with Bran and he seemed to take it okay.
That break lasted 3 months and during those 3 months he didn’t ask to hang out with me he barely texted me but he was hanging out with Bran every week just fine.

I’m not going to confront him about it because I don’t want to start any shit and I tell myself I’m going to stop responding to his messages but I never do I always respond

He sent me a happy birthday and we chatted for a bit and I sent him one on his birthday and he went back to ghosting me again

I haven’t heard from him since . I get friends coming and go but after not wanting to hangout with Bran he’s literally my only friend
