text: same question with different details.  is it o.k. for my son's father to date his preschool teacher? a lot of people answered the 1st time i asked this and i think i need to clarify some things.  my son's dad doesn't need my permission to date someone, but i would expect he would get my permission before he dated a woman we have a mutual relationship with......our son's teacher.  also, i actually like the woman.  she's very sweet and smart and my son likes her a lot, but this is his teacher.  what if they break up?  will she take this out on our son?  is it appropriate that when he spends the night while he's visiting daddy, he wakes up (because he always wakes up very very very early) and sees the teacher half dressed?  my son's father has had other girlfriends in the past and it doesn't bother me at all......but the teacher thing is killing me! as a former teacher, i don't think it would be appropriate at all for a teacher to date a student's parent.  it is a huge conflict of interest.  you are justified in your feelings and you have very valid points and concerns about the issue.
