I Sometimes Feel Lonely

I feel lonely lately. Maybe it's weird to say, but I wish my friends were... more attentive. I'm sick of making the first step and getting silence as a response. I do realize they are awfully busy with their own lives, damn, I get very absorbed with mine. Everyone has stuff happening, everyone has a lot to do, people are always tired and out of free time, but to abandon those who you call friends isn't the smartest move. I know that, because I've been there. I lost an emotional connection with my friends while I was in my previous relationship and when it ended, the world was the loneliest place. I had to make new friends and now I try to talk to them, to make sure they're fine, to keep in touch, but I either get nothing, or a short response. I'm sure I've done nothing to make them mad at me, so it's not resentment, it's just the lack of time that is a huge bummer to me.
Also, it makes me SERIOUSLY irritated when people only want to talk about themselves. Like, chill, I asked how YOU're doing, and expressed interesed about YOUR life/work/emotions/relationship/whatever, I really DO care. But if we chat for 3 hours and you only talk about your own life, job, cooking, family, gaming, dating etc., not even asking "how are you?", you are a pr!ck. I know a person who does that, this is why my relationship with him has faded significantly, I wasn't okay with going through a lot myself and getting no interest from someone who finds time to talk about silly stuff for hours. Now my friends are quiet and I work a lot, but I crave a conversation, a chit-chat, a voice message, anything. My boyfriends spends a lot of time with me, but again, friends are friends and they should be around as much as I try to be around for them.
I'm just disappointed.
