What to look for in relationship books
If you're overwhelmed by the sheer number of relationship books in the self-help section, don't despair. Here are some things to remember.
- Style: Look for the type of help you want, for starters. A book on staying married won't be a great fit if you're newly single and looking to get back out there, for example.
- Issue: Pick up books that speak to your particular issue: Maybe you're interested in learning more about your love language, or you need help establishing and sticking to boundaries. Getting specific about what you want will mean a better chance of finding it.
- Experts: Not just anyone can write an effective self-help book, so look for authors who have the bona fides. Look for psychiatrists, psychologists or researchers who have conducted research in the field or memoirs from people with extensive lived experience to share. Knowing whose advice you're taking can help ensure it's legit and applicable to your own life, too.
How can I improve communication in my relationship?
When it comes to communication, active listening is key. We’ve all gotten so wrapped up in what we want to say that we just wait for the other person to stop talking instead of actually taking in their side of the conversation. Instead, focus on really engaging with your partner, in heated discussions as well as day-to-day chats. It can help to parrot back their perspective to make sure you really get it, by saying something like, “What I hear you said is…did I get that right?” Encourage your partner to do the same, to help you both get and stay on the same page.
