<human>: Could you distill the essence of the text into 1-3 sentences?

So a little back story, I've been dating my boyfriend for about a year now. We'll call him Stan. He has a five year old son from a previous relationship and was very upfront about that from the start and I'm obviously fine with it. Things did not end well with his ex (which is a whole other screwed up story) and she has made it her goal to make sure he has no place in his child's life. This woman is pretty crazy and I'm not just saying that because she's my boyfriends ex. She had a decent sized criminal record before he got involved with her and she is only adding to it currently. She was able to take the child out of state because she had a restraining order placed on Stan claiming that he had hit her. Truth was she gave herself several bruises and had family lie for her to support her claims. There is a long list of other things this woman has done but we won't go there. Stan has made every attempt to reach out to his son from trying to send letters to sending gifts for birthdays and even offering to give her family money to support the child. There's a long custody battle going on right now and it will still be a while before he is able to see his kid. It breaks his heart that he can't be there for his son and it upsets me to see him hurt. 

My question is, how do I handle father's day? We are spending time with both sides of the family that day but I am unsure if I should mention something specifically to him. I know for sure that it wouldn't be right to get him some cliche gift. I have thought about just writing a small note that says how I'm sure he'll make a great father for his son and I'm sure things will work out soon. Or I could skip that and just treat him a little extra nice that day and not bring anything up. Anyone else out there that have been in similar situations?
<bot>: boyfriend has a son that he is not able to see for reasons beyond his control. What do I do for Father's day?
