Suspending a khula

Q: I am separated from my husband for more than 6 months. My husband tries to arrange meeting and reconciliation but I dont want to go to my husband's home. Now my husband sends me notices that if i do not come within a particular date, it will be declared as a khula as I am not interested in any reconciliation done from my husband and he can get married again. If i don't reply or go on that particular date, will the khula take place? What will be the iddat period?
