Me and my ex split almost 3 years back, i took full custody of our ds, i kept up with videocalls, texts about their progress in full detail then i noticed the dad stopped asking about him one time it took his 3 weeks to ask for a call or text in general. I started slowly replying in full detail just breifly text back. Then when they were in call he would barely ask anything and would be a waste of time. Then eventually he stopped asking to vidcall and would text every 2-3 weeks the same sentence how he is, sleeping/eating and school. I would then reply with small detail with photos. He hasn't seen his son inrl for 2 years and the last time he did i paid for my ds travelfare and my ex's plus pocket money for food etc. The excuse for him not coming to see if money, he says its easier for me to get money although i work 20 hours a week as a single mom living alone in a new home. I focus on my ds needs, pay my bills and work plus having to keep up with this parade of him not caring for his son. He would only send some presents around his birthday/xmas but last minute and ask specially what to buy. Therefore he doesn't look himself. Last time we tried to arrange videcall was 3 months back with my ds auntie (ex's sister) which i agreed to then she sent abusive voiceclips to my phone, saying how bad of a mother i am. So i instantly blocked her and his entire family. Now out of the blue he has asked me to start vidcalls BUT with his mom on HER phone.. i know if i do this she'll shout abuse down the phone to me and ask me a million questions which i do NOT need. They only want to know my ds when they want, am i wrong for NOT wanting to take part in this for the sake of my son? He doesn't ask about his father anymore i try keep him alive in his memory. But i can see his frustration if i start the vidcalls or phonecalls it will just get him all exicted again and his father will lose interest again.
