How to be less clingy?

Kelsey

Me and my bf have been dating for 5 months. We are really in love but he says I’m clingy sometimes. I’ve been giving him space for the past few days but it’s so hard to get him off my mind. I know in the future I’m going to have to go for long periods of time without seeing him. He rarely ever has his phone on him so I only text him goodnight everyday. How do I mentally chill and stop obsessing over him?
