I miss texting "I love you, goodnight"

Me and my ex girlfriend broke up in May 2025 but I officially moved out 3 months ago. So everything is still very raw. I've just started to grieve the relationship. I miss her. I see things that remind me of her and I cry. I miss texting "I love you, goodnight." Not just to her, but to anyone. I miss having someone beside me at night when I wake up from a nightmare. I miss feeling part of a partnership. I miss having someone to love me in times when I find it hard to love myself. I feel like somethings missing and it feels very lonely.
