i have tried changing the verts, aswell as the weight paints and so far nothing has worked, with the weight paint it looked ok but the legs were overlapping even with an alpha

My guess would be it's a weighting issue. It looks like thos center verts are weighted to the pelvis when they should probably be 50/50 on the upper leg bones.
