<human>: I'm only male 18 and I'm capable when talking to girls I just don't really know how to interpret their messages and so I never really make a move on them but recently all my friends and even all my siblings have gotten into relationships, for Christ sake even my mum got back in the game

my friends date my other friends and the only single girl i know who has been my friend/crush forever recently got a boyfriend (my heart be crushed).

 I now am the only single person in my life, anytime I go out with friends or family, its couples being couples all around, i often get left walking behind all of them while they hold hands and stuff, I don't despise them but it makes me feel alone in a crowded room, I just was wondering if there is any advice for a single guy surrounded by couples? Any advice really, I just really don't like the way it makes me feel.

Could you distill the essence of the text into 1-3 sentences?
<bot>: I'm the only single person left in my social circle, surrounded by couples whenever I go out and it makes me feel isolated, I need serious advice
