The worst mistakes you could make in your relationship are the ones you don’t even know you're making. PopSugar recently compiled a list of mistakes to avoid making in your relationship.
1. Staying in all the time. Go on date nights, people!
2. Letting things slide. If it bothers you, say something.
3. Getting lazy about sex. Don't let the fire burn out.
4. Skipping relationship milestones. Celebrate, celebrate, celebrate!
5. Falling asleep on the couch. Sleeping with your partner is great for your relationship.
6. Not speaking your mind. Your partner should know all of your crazy thoughts.
It's easy to accidentally fall into the above habits, but break 'em before they break your relationship.
