Turned out my bf still cant get over his ex

There was a person who told me he loves me for months. We had some kind of a long distance relationship. 2 days ago he told me he want us to be friends again because he's suffering from the distance and it causes pain.

He told me that he loves me so much, that he can't focus on his work and his goals. Because thoughts about me are distracting him. He said he wants to keep me in his life, but don't want to put his heart into it. His voice was shaking so much during he said all this. I called him the next day to make everything clear. I didn't understand why he wants me to cut off his life. And I offered my support. Because I wanted our relationship to be healthy

And I wanted to solve this problem somehow, because he said he's in love with me. And I wanted to keep this relationship somehow.

And after 40 minutes of talking on the phone. Bringing up arguments that we should try to continue our relationship. He just told me: okay, do you wanna know the truth? | can't talk to you anymore because I still can't forget my first girlfriend........

It just changed everything He was lying to me all the time I'm not sure about a single word he ever said to me

Because everything seemed so real. His words, the way he looked at me. I can't believe he was using me just to fill the emptiness after his first relationship
