I lived with a man for 20yrs that had affairs every 4-5 yrs. My daughter who is 19yrs old has had father issues since she was 8yrs. Now that she is older she has told me what took me so long to leave her father. Now through her schooling she is dealing with her father issues. It is good that you and your daughter communicate, and it is good that you are thinking of her, think on how much more happy she will not seeing you go through all the things you are going through. My kids have told me, they are happier now that dad is not home anymore. Take care and keep us posted.
