Ya i know how your feeling, it sounds similar to my situation. Freinds think its 'okay' to leave me out of nights out, and stuff, and yet think that i am actually interested in hearing about their nights out after? Ah no. i'm quite defensive and i can stand up for myself, which makes people think im a ***** at times, but its just ive learnt that i cannot trust many and i need to stay on guard. I dont think ive any advice for you, but what i do when so called 'friends' do this is just walk away and move on. But you said these are your friends since childhood, so idk,. Just know you're not alone in these situations.
