I have learned through therapy that I can not say I know how you feel. but I can tell you what I did. I was with my husband for 7 years. He has two children from a previous marriage when I met him his kids were 10 and 11. I basically raised those kids. I not only put up with the abuse from him but from his kids. His son threaten to kill me twice.
I was abused when I was a child. Me and my husband have a 5 year old together. I left the first time when he did not want to do anything about his son trying to kill me,but because of our daughter I went back. Three years later I have left for good when he held me down and wanted sex. I am now happier than I have been in a very long time. I am with my parents and I have custody of our daughter.
Leaving was hard but I had a choice to make do I stay in a marriage were I was unhappy for the sake of my daughter or do I leave for for my daughter and be happy I chose me.
