I'm having a hard time dealing

My now ex boyfriend left about a month ago to Tennessee for a religious camp called Narrow Gate where he can grow spiritually and also learn new skills and find a purpose in his life. He'll be there for 6-8 months. If you know anything about Narrow Gate, there isnt even any communication allowed. At all. So he'd be done with it by the time summer comes around. I still live in Texas, which is where he used to live before he moved. We lived in the same town as well. His parents and his younger brothers moved to Tennessee as well. And since his family live in Tennessee now, I don't see why he would come back to Texas. He broke up with me a couple of weeks before he left, and he was crying. We did spend some time together before he left and it was as if we were still together. There was still so much love and it was amazing. He was saying these things like there's a huge possibility he might come back, but I just don't know. And I don't see why he would because his family lives in Tennessee. I just love and miss him so much. And I don't know if I'll ever see him again. I don't know how to deal with this, and my mind keeps going back and forth between all of this. I just don't know
