I was in love with him for four months, at first it was especially sweet, but then he got busy with work and went cold on me, and when I got anxious I started to put pressure on him, and finally at one point I just left and ended up disconnecting.
Later I asked him if he wanted to make up, but he just said, "We'll see", and his attitude was ambiguous.
This half month I have insomnia every day, I can't open my eyes, I can't help but think back to what we did and what he said, and it's useless to talk to my friends about it, I have a lot of emotional ups and downs, I'm distracted by my work, and I can't be happy at all.
I really want to accept the reality of what's going on and get better, what the hell am I supposed to do?
Hi, I'm Fuji the whale social worker.

Very much understand how you are feeling right now, but we have to remember that before starting a healthy relationship, you have to live your own life first. When you learn to love yourself and run your days wonderfully, there is room to embrace others, and this state of being naturally attracts people on the same wavelength and creates a longer and more stable connection.
But if you always focus on the other person and the relationship, it is easy to suffer and have a messy life, instead of making yourself unlovable. So why don't you focus on improving yourself first, and when you learn to love yourself as well as others, a lot of things will come naturally.
Good luck! (Whale social worker 🐋)
