I left my house heade for theirs with a loaded .40 cal and 2 clips I was going to remove the problem. I thought in the way that they didn't need to see that so I pulled over and put the gun in my mouth.... I then thought of everyone else in my life... My wife daughter and two other sons and man I just couldn't leave them like that. So I averted that crisis and started therapy but you guys saw that coming..
I am glad you made that choise man. I have seen what it does for people when someone chooses that quick and dirty way out. My wifes brother did that to himself. I know he didn't mean to cause all that pain to everyone, break apart the rest of the family and cause all kinds of unbelivable pain and misery for everyone. I guess he just wasn't mentally in that kind of a place where he could have thought as clearly as you did. No one will ever overcome that kind of tragedy and most of them blame themselves for what happened, even if it wont make logical sense, it must be some part of human nature to do so. My own wife ended up trying to kill herself partly because of that too. If I wouldn't have trusted my intuition and left from my work to go to check out on her, she would have been most likely dead too. That is beside the point but illustrates the cascading effects of ones actions quite well. Lot of hurt and lot of burden. I refuse to be part of it and just soldier on.
I really couldn't feel right on giving any concrete advice for you when it comes to your sons, but for what I can gather about what you said, if I would be in that situation I think the best thing you could do for you and for your sons is to make yourself as easy to approach about things they might want to bring up and try to be a good friend for them. Mutual respect, showing that you really care and that you are being honest person can really get one really far.
If there has been that long time for not being in any contact, I understand that there is a lot of excitement and emotions in the air but it would be generally a lot more better for everyone that you would try to remain in control of the situation and rather take small steps in attempts to steer this sh**storm to better direction and that way avoid possible backlashes. Any too sudden action can be too overwhelming for your boys depending on what kind of situation they are in or what reality they have accepted as their "norm". I do have some experience of my own dealing with traumaticed people with a lot of emotional issues, broken childhoods, rape, abuse and all that stuff.
Try not to let your own emotions get the best of you. I know it is hard sometimes but by allowing yourself some mental distance to the whole thing you can see situations more clear and then can adapt and formulate better strategies.
I wish you a lot of patience, clear thoughts, cool heads and all the best! Hope this makes sense to you as it does to me and doesn't sound like I am just blabbering some pretty and all rounded words all around.
