We had our ups and downs but while officially broken up since then, we were still together. Finally she got serious with someone new. Naturally this means we'll not be as close as before (even though she wants to keep being in touch). She did a bad job of breaking the news to me and had been a little shut out about the topic initially even though we promised we would keep each other in the loop fully when we do end up finding the right person. We had both been trying to see other people in the mean time (her having more luck than me) but hadn't gotten serious with anyone. Other than that we were still hanging out and hooking up with each other, until I decided to move to a new city last year away from her. Even then, she came and visited last month. But now, she's really into this new guy and all I've been doing lately is thinking about her, having major FOMO. Feel like she's moving on with life but I'm still stuck. Miss her so much coz she was still my best friend. Lost the person I could open up to, feel like I'm gonna burst. Everything right now almost reminding me of what it was like when she decided to break up the first time and how hard it had been for me.
