Thank you for your question and for using JA. Please click accept so I will receive credit from JA for my time.
I have kept a diary of all the times she has spent away from us.
This is going to be one of your strongest pieces of evidence when you do get into court. This is what I advise all of my clients to do.
Since she is the one that has left that does make it more likley that you would be awarded custody by the court. Until there is a court order, the parents are considered equal since you were married. You do not have to let her see or take the child for visitation until there is a court order. This is a two edged sword since a judge does not like a parent that withholds contact. All you can do is to try and build your case for custody. Here are some factors the judge will look at
Primary caregiver. Who is the main one that has been caring for the child.
Drug Abuse. It is fairly standard for the judge to order that both parties take a hair strand drug test and submit it to the court. Parents who abuse drugs or alcohol will not be awarded custody.
Wishes of the child. The judge may take the wishes of the child into consideration. While this is just one element, the older the child the more weight the judge is likley to give to the child's wishes.
Past custody. Who has historically had custody of the child and has that party provided a safe and stable environment for the child.
Parental behavior. Has there been domestic violence, excessive use of alcohol, criminal convictions, parental kidnapping, or any behavior that endangered the child
Encourages a relationship with other parent. Which parent will best foster a relationship between the child and the other parent. Has one parent withheld visitation to “punish” the other parent or made derogatory comments about the other parent.
Home Environment. Which parent offers the child the best stable home environment. This includes who can best supervise the child at home, the living conditions, what other adults and children, especially siblings, are in the home, the neighborhood where the home is located, which parent will be able to better continue the same school and friends.
Employment. Which parent is better able to financially provide for the child. If the parent works, what arrangements are there for babysitters, day care, etc. Does one parent travel.
Relatives. Does one parent have relatives that have a close relationship with the child.
Health. Does the child or a parent have any health issues that would impact the decision on custody. Which parent normally makes doctor appointments and accompanies the child to those appointments.
Religion. Which parent will expose the child to spiritual guidance and growth.
Relationship with child: The love, affection and emotional ties between the parent and child. With which parent does the child bond more, spends more time with the child, bathes and puts a young child to bed, prepares the child's meals and to which parent does the child openly show signs of affection.
Character. The judge will have to evaluate in a short period of time the character of the parties and whether one parents morality and credibility makes them the best parent to award custody.
Usually it is better to reach an agreement rather than to spend money on attorneys that could be better spent on the child.
