I dont blame you its such conflicting situation and sad. I think the sad thing is if the kids want to speak to him they will ask. I know from experience with my own so called father that from a young age he wasnt interested in having contact or a relationship with me...he does with my 2 sisters...he used to buy them christmas presents and cards and they would try and hide them from me. Do you think saying something will change his behaviour? If not dont put yourself through it. Much love and hugs its hard when it affects your beautiful little ones xxxx
