Can someone help me analyze this poem?

0 "Thief by Alice Major 02br
02br
00You have made the others in this house 02br
00more careful. Locks drilled 02br
00_____In doors. Boards nailed 02br
00to basement windows. 02br
00_____The cats *** cautious ears 02br
00at the covert crumble of leves 02br
00_____in the outer dark. 02br
02br
00You pawed the intimate clinging 02br
00confusion of drawers. Your breath 02br
00mingled with the potpourri that scents 02br
00my shelves. All the time, your face 02br
00in shadow. Your hands, hasty, random 02br
00stupid for what they take 02br
00_____and what they leave behind. 02br
02br
00But you will not make me take 02br
00precautions. I know your face too well. 02br
00You are the thief who, one day, will 02br
00_____seize all 02br
00that I hold precious. You will come 02br
00again, lock-breaker, thug with thick fingers. 02br
00No care that I can take, no shutter 02br
00on my heart, can keep you out. I know 02br
00the scythe-curve of your shadow 02br
00--------on the wall." 02br
02br
02br
00* The 01i00___02i00 means blank spaces. 02br
02br
00There is supposed to be a meaning as why the poem is spaced out wierd. If u got an idea why that is, please tell me. 02br
02br
00OK ... What do you think the poem's meaning is? 02br
02br
02br
00My opinion is that the writer is talking about someone that she's in love with and that person cheated on her before, and now she's afraid that her lover will cheat again, yet there's nothing she can do about it because she's in love with him. "No care that I can take, no shutter 02br
00on my heart, can keep you out" 02br
00By the line "Your hands hasty, random, stupid for what they take and what they leave behind" ...i think it means that she thinks she's better than the other woman her lover cheated on her with. 02br
02br
02br
00If you find any poetic devices (metaphors, personification or anythin else) PLEASE let me know05002br
02br
02br
00Also, if the poem is about love, then what's going on with her drilling locks in doors, and boards nailed to basement windows...? Would that be herself isolating from everything else? 010id5
