So to save his position in the Kingdom Hall your Father is willing to kick you ,and his grandchild out of a house he has formerly allowed you to live in ????
Does that sound like 'true Christian love' or even 'natural affection' ?
To me it sounds like manipulation ,and spiritual blackmail ... Because they know you will be faced with increased hardship without their assisstance ,and this will make you easier to control when you feel you have no other choice than to follow 'the rules' of the organization .
Now is the time for you to decide ,are you going to stand on your own two feet ? Do you want your own child to grow up in a religion that coerces parents to behave this way ?
Do not fall into the trap of guilt being laid at your feet . It is a tool used to control you . You are an adult I assume . You have the right to make your own choices now .
Find sources to help you in your area for single Mothers . Local Churches can be a big help ! Many have programs willing to help a person such as yourself ,especially in a small town .(I live in one myself ,and was amazed after leaving the Witnesses ,how very helpful and truly organized local Churches were in helping those in need .)
Chin -up girl you can do this . Much encouragement and good advice can be found on this site . Courage to you !
