Reconciliation would mean that you are living under the same roof with your spouse as a married couple, including all the actions of a married couple. Sleeping together, sharing finances, spending spare time together. It has little to do with where you spend time with the children. If you have a separate address and are not working on your marriage, then it would not be considered reconciliation.
I understand that with the special needs child, it may be difficult to do, but it may be a better idea to have your time with the children somewhere other than the marital home. If you are separated with the intentions to divorce, then eventually, you will not have a “place” in the home. Especially, if/when one of you begin to date. This is a difficult time for everyone but this year separation can work to help everyone get adjusted to a new situation. I suggest getting some sort of agreement worked out and work out a new arrangement to try. You may have to try out several different schedules depending on the needs of your child, but it would be a good idea to look ahead in this situation. This will also help the other child deal with the fact that you and the other parent are no longer together as married. Every child wants their parents to get back together and by you being in the marital home every day it may give the child false hope that this is a temporary situation.
If it is not certain that you are getting divorced after the year and area working on your relationship, then there is nothing wrong with keeping the same schedule and staying so closely to the routine. This is just my opinion though and you should do what is best for you and your children. Good Luck!
