So there's this closest friend of mine like literally my 1st priority within all my friends. I had been making plans with them while their exams were going on and they told me that it's better to meet once their exams are over. It's been over 2 weeks they went out with every single friend of theirs and even a guy they met on a dating app (first date) and yet never once mentioned wanting to meet me. Another thing happened...so it was my birthday and they didn't call at midnight which is...fine. understandable. I am not a kid anymore expecting calls at midnight. I atleast expected them to text me once they woke up but they didn't remember at all. When I shared a snap to them that's when they remembered that it was my birthday and TEXTED me didn't even bother to make a call and then apologised for not wishing earlier. I feel bad. Why am I last person on their priority list...while they're the first on mine. This is what upsets me and makes me stop wanting to talk to people cause this shit just hurt. People remembering my birthday is a big deal to me. It tells who cares enough to remember it or not and them being my closest friend and yet forgetting about it just hurt sm. Am I overreacting? Or just too eager for their attention?
