Being a true gentleman is not something you can switch on and off at a time of your choosing, and as you pointed out you only acted as a gentleman. I would suspect that your best cause of action is to just be yourself, she needs to like you for who you are and not what you can pretend to be.
Best wishes to you and all those who are celebrating the ancient festival of Norouz. I hope that the 'New Day' brings new beginnings and 1389 proves to be a good year for you and your nation.
If you express your concerns to the court they may arrange for the first few visits to occur with either yourself or a family member present. It is however possible that he may be doing this not to gain visitation to his daughter but to annoy you. The best advice I can give is to contact 'relate' (www.ralate.org.uk)they will listen to both sides and advice on the best way forward.
