Any suggestions?

My neighbor moved in recently. At my request, my husband talked to him and asked if he minded if I take care of his roses because I like them so much and don't have space for many at our place.

My neighbor has a bush that is growing sideways and, with heavy winds and rain in the last couple of months, has fallen over.

It was leaning so much to start with that the roots are not sticking out (It didn't have far to fall.), although the ground has lifted somewhat on the root side.

I think it was growing toward the sunlight and also somebody clipped off the stems on the opposite side( The ones that could have counter-balanced the plant.)

I don't know what kind of rose it is. When I first looked at it I thought it was a climbing. It has lots of stems that are about an inch thick. They are growing long. The bush is probably 6 ft. 'tall' ( It would be if it was standing up.)

It has lots of healthy growth and buds, but has no support.

Should I cut it way back and give it some support to try to help it grow the right way? Maybe dig it up and plant it more towards the sun so it's not stretching toward the sunnier spot? Anyone's help greatly appreciated. Thanks.
