Need advice on a friendship situation and possibly need extrovert people to adopt me

Hi, i have lived here for almost 2 years now and i am friends with these 2 girls who live very close to my place, like 5 mins away.

Its been almost 10 months living this close together but we haven’t really hung out as a trio as much I’d thought we would.

Both of them are flatmates and live together, they are constantly making plans together, going out to eat, hanging out, and i have started to notice that they don’t invite me.

Even if i invite one of them, and the other one isn’t available they will drop the idea of going out completely. They will only come as a duo otherwise wont. This makes me extremely lonely because I don’t have any other friends here, neither my family as i live alone. I don’t know what to do, i have been doing things on my own but honestly sometimes you just need a human to hang around with. It has come to this place and i just feel a barrier around them emotionally, and yes i have communicated to them about this but nothing really seems to be changing. Idk, I desperately need a few friends here dude idk how am i going to survive being this alone.

Please advise and if possible, adopt me and hang out w me.
