Hi Raven
I was df'd last year.
I have the same loving relationship to my parents as before. They will never shun me and I eat with them every week. I just don't discuss much about religious topics with them.
Although I did many things not to get df'd, getting disfellowshipped was good for my life.
Now I am completely free, free to live a good and morally fine life.
I lost all my JW friends, but I am slowly making new friends who won't just throw me away.
I feel for you and wish you all the best. Focus on the good things in your life. Be especially loving and respectful to your mum, so she also should accept and respect your life decisions.
If she intends to shun you, you could ask her if she would shun her grandchild if you would get pregnant.
