Talking to my ex

Me and my ex are talking again! I feel like we're dating but just not officially. I've really missed him and our time apart made me realize how much I love him. I tired to move on with other people but it just wasn't the same. I'm so glad to have him back in my life. I hope things stay good like they are now. I want to date him again but I'm so scared of committing myself to him again bc I got hurt last time.
