You can grieve anything: a death, a situation, a loss of some other nature. It's quite possible and not an insult at all.
Welcome to the forum
Establishing inner balance is key to effectively deal with the emotions from separation, which is similar to death, as it is a loss, albeit not final in your situation, with an element of hope perhaps.
You may want to consider counselling, to achieve this under the guidance of a professional, who has experience in this field.
Last year I experienced, the sudden loss of my younger brother
and a few months later the loss of my mom. It was difficult to deal with
the grief, however, my Spirituality, helped me through this challenging
time of my life. Daily Meditation and Prayer gave me the Inner Strength
to seek Understanding and find Peace within my Soul.
Also, I continued my daily Lessons in "A Course In Miracles"
(it's free online) and interestingly enough, it seemed that the right
words kept coming out of my mouth, when I was consoling my dad,
who was just devastated with the two deaths of his loved ones.
It was then, that I realized that being able to bring my Dad to a place of Peace and Acceptance, was indeed a Miracle!
Pray, Meditate, reach out and connect with friends, spend time in nature,
and always remember, you are NEVER alone, unless you choose to be.
Love and Hugs!
