How to recreate excitement in a relationship? Make him miss you how?

Me and my man have been dating for about six months. We get along really well and we love each other very much, but I am finding that we are bickering and when we are not our time together can be pretty dull. We both have stress in our lives which is a downer, but I know that it can be so much better between us. What are some tips you have for me or what do you do yourself to create excitement. I also want my man to yearn and miss me lke crazy like he use to..
