The only way to get relationship experience is to be in a relationship. Every relationship gives you a great deal of feedback regarding personal desires, boundaries and standards, so each relationship you engage offers value to all involved, if you approach it from that perspective. 

We focus on the ending or we keep score of what is going wrong, instead of allowing it to teach us more about who we want to be, what we want to draw from others and how well we can collaborate with those we love. 

Don’t be so hard on yourself. Give yourself ease. You are learning and growing. Let the experience provide you with information and empower yourself to move towards what you desire.
