Meaning of "Instamatic" by Vertical Horizon

The lyrics of "Instamatic" seem to revolve around a toxic relationship where one person takes advantage of the other's vulnerabilities and emotions. The reference to 'lost causes' as something that turns the other person on suggests a sense of thrill in pursuing and manipulating vulnerable individuals. The speaker feels used and betrayed, as indicated by lines like "And the memories are mostly Instamatic, What's left of me belongs to you." The comparison to battleships waiting for a call highlights the feeling of being trapped and powerless in the face of someone who is callous and manipulative.
