If you ask anyone who has been in a relationship, they will certainly tell you that they are not easy. Of course, there are a lot of good times and great things that can come out of them, but still your relationship is defined by how you handle the problems that can arise.
After about a week of soul searching, you may contact your ex and tell him or her how you feel. However, you do not have to go overboard and start begging or crying to them. For sure, the last thing for you to do is to sound clingy or needy.
