Hey just know this is a vent and sorta a ask for advice

ive had my best friend for 7 years. HES MY BEST BEST BEST FRIEND. And I also have another really good friend ill call my best friend bob and the other one james now james is a demi boy but was originally a girl anyway we all staying the night at my house and i wanna sleep out there with them, i felt kinda excluded and i was also really missing my brother that night. So i went to my room to just feel like i was the one excluding me since they probally werent. they were looking at eachothers phones and like idk laughing and shit and talking about it but im not in the fandom. ANYWAY later in the night they were fucking cuddling (EXCUSE MY LANGUAGE) One bob has a friggn girlfriend two james doesnt date cis-males. 

ANYWAY its now the next day everyone was still here, james gives bob their vrc which they never give anyone. I FELT TERRIBLE have no idea why it was fucking nothing anf nothing dmfuckinh magttrrs. Then they play all night after they left. i just feel a bit yk ignored. AND I KNOW LIKE no one will see this but it felt nice to let go of this and get it off my chest. Anyway back to the thingie they have been playing 1 on 1 for 5 hours. HOW DO I KNOW YOU MAY ASK. Ive been waiting for them to invite me ig because ive been on for 6 hours. just. fucking. waiting. 

NOW FOR THE MOST IMPORTANT FUCKING THING>>>>>>>> They are only friends because of me

please tell me what to do
