5. Rereading an old birthday text
“Particularly when I’m alone on my birthday, or something, rereading an old text could be really dangerous. I’ll get lonely and really start to regret that decision.” Men start to think back on their exes when they’re lonely. Get in the habit of sending your boyfriend sincerely affectionate texts and e-mails, so it’s your messages he wants to reread, not hers.
