Ex boyfriend

We were together for 2 years. we're so controlling when it comes to each other. It's been a little less than a week since our breakup and we haven't spoken since, then all of a sudden he calls me telling me he misses me and loves me. And then freaked out when he found out I was talking with an ex. He's still trying to control me even though we aren't together. I love him and miss him like crazy and I feel like I'm getting sucked back in. Should I stay strong and move on or should we try again.?
