Thank you for that information - and I do understand your frustration with the site
I am also sorry about the site popups - if I could turn them off I would.
As you are aware your ex does not have Parental Responsibility for your daughter as he is not named on the birth certificate and you have not signed a Parental Responsibility Agreement
However the law says that a child is entitled to have a relationship with both parents provided that can be managed safely.
The right is that of the child - not the father - which I can see youbelievee as well
If you are certain that he is in fact the father then it would be unwise to say he cannot have contact because he have said the child is not his.
This is not because it would be unreasonable - after all he is the one being stupid, but because it would not be respecting your own wishes for your daughter.
What you can - and should - do is continue to say clearly that your ex needs to show that he is committed to having contact with the child; will not dip in and out of her life AND will build the relationship at her pace and not his!
I would offer contact at a local Contact Centre for a couple of hours a fortnight suggesting that it move out of the centre after, say, six visits and builds up slowly in terms of time from there
If he accepts it - great - if not your offer is reasonable and if he chooses not to accept it that is his choice and not yours!
I hope that this is of assistance - please ask if you need further details
