Ex boyfriend

A couple of days ago my ex boyfriend decided to break up with me, while I was at his house (2 and a half hours from home). Which was only 2 days after our 1 year anniversary, which crushed my heart into pieces 😖 once I finally got home he decided to call me and told me he'd made a really big mistake that he'll regret for the rest of his life and that he wants me back. I don't know what to do because I still love him a lot but I'm scared he'll do it again and it might be awkward 🤔 HELP!!
