OP...I have been in this situation and believe me, the damage is so far reaching. I was in a worse situation than you in that I had a child with him... (he went on to sexually abuse her when she was only 2/3) and he emotionally abused my DD1 and my DS. We had also moved overseas and I had no one to help me. However, I always shielded the DC until I could escape. I took the flack for their 'wrongdoings' to protect them, and constantly told them it was him, not them. Then as soon as I could, with the help of the police, we fled.
DS got the worse of the emotional abuse. He was 5 when it started and now, at the age of 16, he is only just coming through the effects of it. My ExH hated him, despised him, was disgusted by him. Constantly told him he was gay, a faggot (his words) a poof (likewise)...and it made DS question himself when he hit his teens, terrified that he would indeed turn out to be gay. he was scared to eat at the table in case he dropped his cutlery, or spilt something, or spoke out of turn. Eleven years OP....eleven years of my beautiful little boy's life spent in confusion and turmoil. Please don't let this happen to your DD.
This was all running at the same time as DD2 was being sexually abused, as was I, and DD1 was being emotionally abused (she is made of stronger stuff and would stand up to him, even from the age of 7) however I don't know if there is any damage beneath the surface.
We were left homeless and penniless because of him, but I had no choice; I'd have lived in a cardboard box away from him rather than a mansion with him. the weeks we spent in a women's refuge were among the happiest of our lives, purely because the DC were free to be children.
Please...don't allow this damage to happen anymore.
