I'm feeling really raw, vulnerable and out of control and really need some help here. Im so sorry this is long but I need to give a timeline of events. Please be kind to me
Ex lives 10 mins walk away, we divorced last year and it's been gradually getting worse with comms, we now no longer speak and I am taking him to court for a financial order.i still try to however keep the peace and remain flexible and mature when it comes to childcare arrangements.
Finances are a long side story but I escaped a narcissist and he currently has the business I built with him, the assets, the beautiful work live studio and now a gf 16 years younger. Relevant because I'm broke, only 1 year on still recovering, can't afford fancy gifts and trying to make the most out of cold parks and play dates.
I am primary carer of our 10yr DS, ex sees him Tues after school for dinner and sat over night, despite being down the road this was his choice. He loves his son, they love each other but he loves himself a lot too..
Xmas fell on sat and so with no discussion plans were made starting Saturday morning, to not be confrontational I planned a dinner on Xmas eve with my single mum friend who has a similar age ds.
The gf likes gaming and Harry Potter it seems and DS keeps coming home to tell me about all the cool consoles she owns. Ds receives latest PlayStation and about 8 games for Xmas from ex.
My son announced he was attending dad's NYE party, (Friday) I didn't want to be difficult and I had no other plans and agreed
His father emailed about taking son to Harry Potter studios on 3rd, I agreed but raised the same courtesy should have been shown in regards to nye esp as it wasn't his day. I explained as I had no better alternative plans for ds it was OK to take him on both days (I think I was wrong to do this )
Ex swears my son claimed I had party plans and was dropping him at friends house so he thought it was a favour.
DS spends Fri NYE at dads
Doesn't answer phone on sat morning
Calls me Sat at 3pm to say on his way to grandmother and his dad assumed as it was sat he was staying over 2 nights. I am disappointed but think its a misunderstanding. I remind DS we have dinner plans with friends on sunday, In my mind I wanted to make up for lost time and also take him to the park on sun to play basketball
Sun I call, no answer. Ds calls at 1. Going for lunch with grandmother and already in the car??? Ds is rude when I raise my voice and lose my temper, and groans he will be back for dinner I hang up humiliated and hurt as I know this conversation happens in presence of ex and gf and I look like an insane ex wife.
He is home by 3. I Talk to ds about how he should consider my feelings and communicate with me and answer his phone. We go for dinner, no park its too late. I have had no quality time with ds.
Next day Harry Potter with dad and gf. He calls at 7 they just left the tour he is in the car and catches me off guard and says, mum you don't have plans for tomorrow right? I say nothing concrete, so he says OK- hey dad can I sleep at yours tonight ?
So another night at his dad's (last night) and I have never been away from ds so much. Its because of the PlayStation and fun girlfriend
I experience a cocktail of emotions ranging from range, to jealousy and pain and as much as I try to maintain composure I text his dad and say its been a pisstake week of my time being disrespected and if he does not want to liaise with me directly and clearly on childcare then I shall get a court order.
Ex replies, well he caught us both off guard and he obviously wanted to be with me. 
3pm ds calls, I say I'm in aldi and will pick him up when done, ds says no dad will drop me, I say no ill pick you up, ds insists dad will drop him, I get frustrated and hang up.
Way back home and I tell ds ill be 5 mins from his dads
DS. Says but we agreed dad will drop me that was the plan, I say we'll I'm here, ds says that wasn't the plan. I lose my shit.
DS cries, I tell him if he doesn't want to come home ill pack his uniform and he can stay at dad's.
Ex calls me and says I'm being mean and it's bad for ds and its a misunderstanding. Cue crazy looking ex wife again and perfectly performed gaslighting. I pick ds up, he goes to room texts his dad. That he hates that I'm so mean.
I saw his phone. I got upset, irrational, I lost control and told him if he hates me so much he should go to his dad.
DS. Did not bat an eyelid packed and left 😔
I never shout I never lose my temper, and I did it 3x this week. I'm aware I felt jealous and lonely but my time was also being disregarded. I could have made plans to at least distract me this week. Instead I've driven a wedge between ds and I and ex looks like the saviour and I have lost control that I don't know how to reclaim. If you read this far, please help
