Am I being used?

So my boyfriend "Avery" (M16) is a stoner and an alcoholic. He was pretty sweet at first, prioritizing me over alcohol and drugs and being pretty obviously infatuated with me. Then gradually he left me on read day by day. First, his excuse was TV. Then drinking and drugs. Then gaming.

Now, it's his damn boyfriend. He doesn't even care about me, evidently.

Avery is dating this dude Alex, and at first they were friends who regularly called. That's why he was "too busy" to hang out with me.

"He said he’d love to call sometime and I’m sure he loves us equally, but he calls Alex for hours a day, for like 5-12 hours, and barely acknowledges my texts, he just reads them. In fact, he asked me to hang out with him but that was because he was bored that Alex wouldn’t be coming over."

"They sleep on calls all the time too at night and I’m trying not to care but I’m sad because he spends more time with Alex than me. I wanna sleep over at his house sometime and do all the stuff they do but he can’t because he’s always busy with Alex." is what I posted before.

It basically sums up my post from before. Now, I asked him if we could hang out actually and do stuff together and if he could love me like he used to and he said "Honestly, I don't really know" and that he doesn't wanna hang out with me, only Alex.

I hate that guy so much right now and he pisses me off, "honestly". That's my honest opinion.
