Am I overreacting to his suicidal comments to our counselor?
I think you need to schedule an "emergency" or "urgent" meeting with her to discuss this. This is NOT an area for miscommunication.
Did you ask her this question? I can understand if you did not, that a state of shock (and a zillion other emotions) can make it hard to think.
Did the suicidal threats get made to the counselor and counselor only? This is what is sounds like. I'm also assuming your counselor is properly credentialed and licensed mental health professional.
If that is the case, then I would follow their lead and SPECIFIC direction on what to do if he make those threats to you. Let them use their training to decide what to do if threats are made to them.
Am I underreacting to his suicidal comments?
I wouldn't even want to hint at an opinion on this, without clearly understanding the opinion of the counselor.
My basic advice is to take all threats made to you seriously and YOU should act on them BECAUSE you don't have the professional training to properly assess and handle them.
I'm assuming your counselor does.
What are some things that I can/should do to protect my S14 from the impact of any potential suicide threats or attempts?
Again... .ask the counselor for specific direction. Ask if you should prepare them ahead of time (which would likely be traumatic) and then potentially never happen.
Is there any point in me letting my husband know that I'm aware of his suicide related comments?
Ask the counselor.
Absent specific direction from the counselor I would NOT let the husband know ANYTHING the counselor has shared with you. ANYTHING. If the counselor wants the hubby to know something, let them reveal.
Should I start getting ready to take on more/full custody of our S14 to keep him more insulated from my husband's actions? (I believe the suicidal talk stems from fear or losing our marriage and I fear that "taking away" our S14 would only add fuel to the fire)
Preparation is ALWAYS a good thing. Done privately. Taking action is where the real wisdom lies. If you feel unprepared about any part of your situation, privately preparing, especially under the direction of the counselor, is likely a good thing.
Have any of you dealt with this type of situation and have some wisdom to share from your exerience?
Luckily the answer is no for my personal relationship. In my professional relationships (Navy), the answer is unfortunately yes. I have ordered several individuals to "med hold" for evaluation based on suicide threats or even hints. Zero tolerance... .no... .nada... zip... .
The reason is that I'm not a doctor.
There have also been times when I have sent people that are "clearly distraught" but have not made any hints or suicidal statements.
Granted, in the military there can be unusually stressful circumstances (compared to civilian life) and our protocols get tested often.
I will also say that getting cleared out of "med hold" is not a "black mark" against you. If you don't get cleared... .then there are bigger issues than worrying about "black marks" on your record.
My advice would be different if there was NOT a counselor involved. It would mean a lot to me if you could share the counselors direction with us... .or... .if you don't have specific direction, that you seek that immediately.
