codependency

Hi, recently I have found myself to be very codependent on my boyfriend. He is a hardworking guy who sets a lot of goals for himself so he is very busy. I of course support him but sometimes I feel very lonely and it makes me need constant reassurance. I find myself relying on him for happiness and when he’s not able to be around me i become depressed and i let it ruin my entire day. I realized that i am not considerate of my own time because I make sure I am free when i know he will be free. All i worry about is making sure we can spend time together. I really want to work on becoming independent and not letting this weigh down on me so much. besides me being so codependent, our relationship is healthy. can anyone relate?? any tips or advice??
