Hi there i need some help i dont know much about plants/Trees but i thought id lend a helping hand and cut back this plant/Tree,

the partner wasnt so happy when she saw it afterwords i dont think it looks to bad considering it was twice the height myself , however my main question is does anyone know what type of plant this is or tree.

befor it was arround 12ft high until i trimed it down,

But the partner thinks i have killed the tree now so wasnt shure as if i have killed it or not, or might have to go and get another one if i knew what type of plant/tree this is ,

It has been moved about 3 to 4 times in the past and seems quite strong,

ive took some photos this morning see what everyone thinks any advice would be greatfull , weather or not i might need a new tree or will it just grow back,
