I will never know for the life of me why the RP does these things, when you see RP on here all the time wishing that their XP / XH would at least have something to do with their DC.
P, (not been DP for a while now, another story,) has a DD who started secondary yesterday.
I honestly think he puts on a front now so he doesn't look how hurt he feels at missing out.
She went NC with him for a long time, i believe it was to appease her DM, the dynamics of that relationship are, well, abusive imo... anyway, she broke the NC to demand an Iphone, which P duly provided despite me not agreeing with it, shortly afterwards, it transpired her SDad had brought it off her because she had dropped it and broken the back screen, she got a cheaper phone, plus £150, whereas SD still had his, brought at the same time, and had taken good care of it..Once the phone was in her hands, she promptly went NC again. She broke the NC again recently when her 'new' phone got a broken screen, her messages to P were along the lines of 'please daddy, i need a new phone, i love you' so of course he was ready to trot off and buy yet another Iphone, this time though, i stamped all over the idea, pointing out that £150 from the sale of the other phone was enough to buy a new second hand smart phone, and it would be unfair on SS who had taken good care of his phone.. he said this to her, she announced she had spent £50 on sweets and crap, and her mother had taken the other £100 'to look after for me' and she hadn't heard about it since, and as regards SS, 'daddy' could always give him £100 to make up for it.

She asked for an iphone 4, the one she sold was a 4s.
So as i was due an upgrade from my 4, i handed him mine to give to her.
Problem solved i thought.
He dropped it off (i think he hung onto it for longer as he was enjoying finally hearing from her) I wasn't there, but apparently she stuck her head out of the door, grabbed the phone, chirpily demanded to know whether it was a 4s or a 5, he said it was a 4, she looked majorly pissed off, told him that it 'wasn't GOOD ENOUGH' then said she was 'soooooo tiiiiiredddd' and shut the door.
I felt so sorry for him when he came back :(
A week later she called to tell him the phone was broken, he said he'd pick it up on saturday (this was last wednesday) get it fixed right away.
At 12 midnight he got an absolutely vile message, i know swearing is allowed but i shall just say one of the words was the 'C' word, and the rest wasn't much better.
Also that her phone had been fixed by 'the best daddy in the world' her SDad, ... The texts flew backwards and forwards, with P getting angrier and angrier, and the return texts getting more and more vile, then he blocked the number.
He's since found out that the previous phone was given to Sdads son.
In a way, i was pleased for once it wasn't me on the receiving end of the abuse, but the manipulation and everything else involved makes me sick.
Fwiw, 'best step daddy in the whole entire universe' is constantly cheating, the latest was a woman at SD's primary school who then started verbally abusing 11 y/o SD.
I wish i'd have known all this, i feel sorry for P, and try to support him, always have .. but his life is a drama from beginning to end that i really could do without.
Make sure please, partners, that you're not being dragged into a world of crap and supporting someone through something that will probably never end
