I have half of a mesh with the weight paints and rigging all set up as shown here: Starting mesh

And if I do a mirror modifier, it just copies the mesh only and both sides are moved with one side of the rigging, which I don't want: Mirror modifier

So I tried just doing the copy paste method then mirroring to the opposite side: Copy Paste

And it looked pretty good, since I was able to control both sides with different parts of the rigging: Separate rigs

So I did Control + J to combine the two meshes... ControlJ

But then this happens, one side of the rig gets both sides of the weight paint for whatever reason Both weight paints

While the other side loses it's rig capabilites and doesn't move anything anymore No weight paints

Is there any way to combine the meshes while maintaining each separate weight paint, or is there another easier option on mirroring the half-mesh? The model used to be a full non-mirrored model, but it wasn't symmetrical so I just cut it in half with a boolean modifier. When I applied weight paints to the right side (left side from the first person view of the model) everything was fine but when I tried adding weight paints to the other side, random parts of the model that didn't have any weight paint were moving along with the rig, so I thought that just cutting it in half, mirroring it, then joining it would be the more efficient option, but it's not working.
