Welcome. I just want to add that I also struggled with the concept of getting a divorce for a long time. I come from a very strong Bible believeing background, and I didn't allow divorce to be on the table for a very long time.
For me, it finally boiled down to this...I was modeling a very unhealthy, disrepectful marriage relationship for my girls. I finally decided that:
1. I did not want them to grow to seek the same type of relationships.
2. I was so nutty trying to deal with my pain, anger and resentment, that I reached a point where I was not emotionally available for them as they needed me
3. By getting a divorce, I was not "taking away" their Dad. He will always be their Dad no matter what happens. Always
That helped me put things into real perspective.
I do understand where you are coming from. And I am a firm believer that we all come to a place where we are where we are suppose to be at the right moment in time.
Glad you came here. Hope you find some strength and hope in some of the posts. I know I did.
