There are some who may find that they are preoccupied with their natural parent or son/daughter that they need to be sure not to shut out those people who have been supportive and encouraged them and are part of their lives.
It is common for triad members in reunion to want to touch, spend time together, talk and share. This is part of the bonding process which is what was cut off at the time of relinquishment and is often referred to as genetic attraction. We have talked about genetic sexual attraction where these strong emotions that triad members experience may stimulate sexual feelings between brothers and sisters who have not grown up together. This can also happen between the adoptee and natural parent. If you are aware of this in advance you will understand and not act on these feelings. Acting on these feelings can be very destructive and seriously damage not only the relationships of the triad members reuniting but also the existing relationships with partners and adoptive family members. I urge you to seek professional help if you are concerned that the relationship is moving towards a sexual relationship.
Reunion is the opportunity for adoptees to know about the circumstances that led to their adoption and to have information about their natural family It is an opportunity for natural parents to know about what happened to the child they parted with decades earlier and be able to explain their actions can go a long way to healing the wounds left by the experience. The bottom line is that no matter how much contact, even if short living, I think that it is safe to say that the majority of people feel a sense of well being and ability to move on and make other decisions in their life.
