Hello to my beloved community.
My boyfriend's dad passed away today from cancer, after battling for over a year. His parents were divorced and he has been living with his father since he was 15 (we are both 27).
Even though I am in a relationship with him for only three months, I feel so connected to him. I had only met his father once, and I feel so sad and sorry for my boyfriend. I mean how do you deal with your partner's grief? Will he keep wanting me as a partner/friend/etc.? What can someone do to support them? Especially in such case, in which I suffer from anxiety attacks, GAD, and even an anxious thought makes my stomach hurt and I then have to rush to the toilet? I feel so weak...

Any advice would be much appreciated.
Thank you in advance.
