1. Don't lead with your emotions. If something happens unexpectedly try not to react with anger or frustration. Take some deep breaths and refocus yourself to think before you speak. As we all know, words hurt more than anything else. They can either make or break a relationship.
2. Don't take your bad day out on your loved ones. More than once my boyfriend had said to me, "I'm not your co-workers, I'm your boyfriend who loves you." This immediately helps me to refocus and start to think before I speak.
3.Try not to take your work home. Allow yourself to vent if you need to let things off your chest but then let it go. Don't have all of your relationships be consumed my work.
4. Remember the good things. Hard times do come around and lead to fights; I promise you they will. Just remember to not only focus on the fight. Focus on why you love this person and why you are in the relationship begin with. If you can't find a reason other than the sex, then you are in that relationship for all the wrong reasons. It's not fair to you or your significant other.
5. Live in the moment. This one is especially hard for me because I'm a woman and a nurse, so my mind is continually going about 100 M.P. H and in about 100 different directions. In fact, as I am writing this I'm also watching a TV show and could still tell you what is going on. When you are with your partner, live in the moment. Maybe just get lost in their eyes and focus on them and only them.
All of these things I work on everyday because I know that I don't want to lose the greatest thing that ever happened to me.
