If anyone has any advice I would be so grateful, I'm sat here crying my eyes out!... Am not even a 'proper' single mum, as some ppl have pointed out to me, as I share care of DCs with my ex. Older DCs I was truly by myself but it was actually easier. Am not co-parenting, but counter-parenting with my ex. 50/50. He hates me and does anything he can to make things difficult. Tried to do something nice this year and take DC out of the country for the first time but... It has been a disaster. Staying with older (but active, young-at-heart) cousins of my DF who I was extremely close to growing up, to save money. DCs have fought constantly, and I mean literally every time my back's been turned. Elder DC is a tween and has been really nasty to me, has said some really hurtful things. Relatives seem aghast with how much screen time DCs have (compared to their own DGCs) but it is the only way I can get mine to behave or be quiet or not at each other. I'm so very tired. I really wanted a nice trip with them, they are only with me half the time so it feels like I have just wasted it. I'm gutted. No idea what to do next year. Just feel so dejected. Don't know anybody who does 50/50 or indeed anyone with a really nasty ex so despite trying my friends will not understand why I am so sad. Plus sense of this being a real 'first world problem' as I am abroad, with DCs, being spoiled rotten by kindly relatives.
