Not here to judge either way. But, I have been doing divorce research myself this evening and came across an article you might find interesting OP. Basically, if you relocate your DD away from her father then you are possibly increasing her chances of developing psychological difficulties and economical disadvantages in adulthood.
According to Family Law Attorney Leslie Ellen Shear, "once a child lives more than twenty minutes away from the nonresidential parent, sustaining the relationship between them necessitates fragmenting the child's life and activities." By committing to the idea of avoiding parental relocation, divorced or separated parents can help children enjoy the best possible scenario that could happen after a divorce - frequent and natural contact with both parents combined with minimal disruption to the children's lives after the divorce.
Twenty minutes away appears to be a threshold for a significant change in the relationship between the children and the noncustodial parent. Beyond twenty minutes, the impromptu visits diminish, and the parenting time with the noncustodial parent becomes more formal and scheduled. When parents live more than one hour from one another, another change in the visitation schedule occurs; the viability of day visits disappears and the children have to rearrange social activities and time with their friends in order to comply with the visitation schedule.
Many studies have correlated children of divorce as having an increase chance of several psychological issues. Children of divorce have been shown to have lower grades, increased school dropout rates, an increased chance of experimenting with illegal substances, lower self-esteem, fewer friends, and several other issues. But, these statistics are all correlational - not causal. In other words, the studies do little to show that the divorce itself caused the issues described.
One of the issues with the correlational studies is that some children of divorce do quite well. In each study, there are three significant risk factors that drastically increase the chance of children having negative physiological problems after a divorce:
Conflict (High-Conflict Parenting)
Distance (Parental Relocation)
Parental Alienation
Without resorting to bird's nest custody, committing to high-quality parenting techniques and living close together during the children's childhood is thought to give children the best chance of adjusting to the divorce in ways that do not lead to psychological problems later in life.
