if he does not want contact that has to be accepted.
But you aren’t accepting it OP, nor are you being accountable….otherwise you wouldn’t be blaming him for ‘causing issues’ ….as in your title.
He isn’t causing issues is he, he is staying away from you both so as not to cause issues. Your husband was the one who walked away from him. He caused the issues encouraged by you. Your husband abandoned him and instead, chose you and a new child over him. Devastating.
Imagine it happening to you and your little boy.
You also say, as do many posters here quite rightly, that you feel sorry for your own child as it’s not his fault. Of course it’s not your child’s fault. He shouldn’t be suffering through this.
But OP, that’s exactly what the ex wife was thinking/saying when her husband was about to walk out on them both. As you were gleefully delighting in having caught your new man, you were completely disregarding the pain of his wife and son’s suffering at the very same time.
It wasn’t then and still isn’t now, that boy’s fault.
Yes it happened a long time ago, but as your husband now knows, the guilt doesn’t go away, it only grows unless there is proper accountability and reparation. Strong emotions like that can’t be swept under the carpet. They leak out. And in this case, they leak out every time your husband is reminded about it…when you are celebrating your own son. That’s the burden you have to try to shoulder, without complaint, to make the best of it for your own little boy. I’m sure you are trying to do that anyway.
Other than wanting the consequences of your long-ago actions to miraculously disappear, I wonder ….what would you actually like to happen now OP?
Have you ever tried to contact your husband’s first son to allow him to express his pain and grief and to talk about to what degree your actions with his father screwed up his life. Have you genuinely taken any of that on board and felt sorry about your part in it.
Have you talked seriously to your husband about his deep guilt and tried to be understanding of it, relieving him of some of it, if you possibly can, instead of being irritated by it. And instead of feeling short changed by it?
I personally think that the more you both really get to grips with properly accepting your own part in past events, bringing them out into the open, the more scope there is for healing and happiness.
We all have to be deserving of the happiness we seek.
I think it’s very good thing that you are beginning to think about it all OP.
Wishing only the best for you all.
