She can't just let him be/is hard work because deep down she's so unhappy and she doesn't know why so she can't fix it (she needs therapy) so she changes everything around her hoping that will be the thing that clicks and changes everything. Katie price does the same. New country, new county, new house, another child, I'll be a photographer I'll have a clothing business, new car, new pet, posh food, new dress get engaged, do up the kids room, buy this, buy that, drink gel tampons, do yoga, whatever. Then it doesn't make her happy and it's on to the next thing.
Another thing she does (actually most people like this) is try and pull others down to make herself feel better eg Billie. Helicopter ride, buying the clothes for all bits that Billie wanted for Minnie's and if you watch their towie bits back you can see she often gives her backhanded compliments she still does now from what I can remember but I haven't seen the show for ages.
Until she addresses the root cause of her unhappiness she will choose unsuitable men (mark, joey, bbp) and will constantly be floating around looking for the next kids birthday party, the next career, the next anything to suddenly change her life and make her happy. And she will be hard work and not very nice until then as well!
Suze has done a lovely insta post for Greg's birthday, does anyone know if she did one for bbp?
