My vehicle needs jumpstarted every time what can be done to fix it?

Hi I'm having lots of issues with my 2000
Ford expedition my issue being every time I
get in my vehicle there's clicking coming
from the front fuse box and the lights are
going like crazy even well after the doors are
shut and my battery is of course dead so I
will jump it and everything will be fine until
the next time I try and start it my battery is
fine the levels in with the water are fine and
the connection terminals are fine and there's
been issues in the past where my starter
wire has been cut by an ex he's very
mechanical and I think he messed with my
vehicle again but I can't seem to figure out
what he did.
