Full of Doubt is right.
They are accepting of you now, because they want you to join them or like them. It's kind of like when you go on the first date with a guy. He will bring you flowers on that date to IMPRESS you. Marry that guy...10 years later you won't get flowers all the time.
Now as far as this shunning thing goes...listen to my story.
My husband was disfellowship. Yes he was repentant....... he hasn't commited this SIN again in over 10 years........10 years later ( that is over half your lifetime).. they still haven't reinstated him... eventhough he has asked to be. I think 10 years of not commiting the sin should show those men he is repentant. Jehovah God knows he is. But because of the egos of 3 men, they won't reinstate him.
When I was 5 years old my brother was disfellowshipped because of drugs. I continued talking to my brother, remember I was 5 years old. An elder had a talk with me in my kitchen he told me " If you continue to talk to your brother you will die at armageddon". He had me in tears. 5 year olds shouldn't have to decide if they should love their brother or not and shouldn't have to think about their own death at the hands of God. That is wrong..unloving and unchristian. My brother is now a family man, sucessful and a very good person. I still love him and I still talk to him. This happened 30 years ago...they still haven't reinstated him.
Now because of all of this.. I won't let my daughter get baptized. When my daughter grows and comes back home to visit she will talk to her mother and her father. I won't let someone tell my daughter you can't talk to your father because he is disfellowshipped. Because that is wrong. Ask your teacher about the scripture that says " honor your mother and your father"... how is not talking to them honoring them?
