Yes to all of these! #1 is especially important for me, personally. People can be VERY adept at hiding who they are with words but, given enough time, they never fail to reveal their true selves through their actions.

Also, complaining about past partners is a huge red flag for me...especially if a person has a long string of similar experiences/stories. In retrospect if I were to have recognized this red flag when I was younger I would have been spared so many hard lessons. Usually the more a person does this the less self-aware they are and it's an accurate indicator of how problematic your relationship with them is going to be (get ready to be blamed for absolutely everything). Lol.

Great contribution to Memoir Monday my friend! Thanks!
