I see and agree with your point wholeheartedly. IMO, Terri took it to a new level in that dept. as it is now blowing up in her face. If this venting was also part of her plan to look innocent after Kyron disappeared, I don't know, but if it was, it failed.
Venting can become unhealthy and only fuel the fire. A lot of spouses don't know how good they have it, but I do. I learned that it isn't who loves us, it's who puts up w/us.
must say i agree with that. there are people out there, who, once they vent, are able to get past what they vented about. when said incident comes up in future conversations later on, usually we end up laughing about it. 'oh yeah, remember when ....' venting can be healthy if we learn to let go once we get it out of our systems. most of us have been there, done that, right? its when you can laugh about it that you've allowed yourself to heal, move on and grow from the incident.
but when we allow it to stew and fester, and continually vent about the same thing(s) over and over again, refuse to forgive and get past it, keep it all inside and to yourself - thats when it becomes unhealthy. feelings of anger, resentment, rage, revenge, inflicting emotional pain and suffering, and so on, that it reaches not only unhealthy but dangerous levels as well.
add to that someone of terri's mental state, and you have a kyron waiting to happen, unfortunately. an innocent bystander who never wanted to be in the middle of the bovine scatterings going on at home to begin with.
its too bad terri was too selfish to allow kaine to pay that gawdawful child support and allow herself a possibility of peace of mind without her thorn in her side in her face day in and day out (as i imagine she felt towards kyron, in addition to the hatred she was drenched in).
but after awhile, she would have been back in that dark miserable place. because of who she is, even with just kaine, the baby and terri, she would have still been miserable.
