Help please

When an ex gf tells you after seeing you again in months post breakup. She never stopped loving you, she can still feel you, the months apart were agony, smelled my cologne, can see me everywhere, hugs me, kisses me. Tells me the chemistry is there and the live is there, becomes very happy in person when im there. Spend the night together, cant let you go and unblocks one of your socials cause you will always be there for her. Then many nights later, tells you she doesnt feel the same about you, is very cold, is sad and trying to cut you off. Says we shouldn't talk or see eachother again, even if either one of us wishes for it. Says shes really sick of feeling sick and sad about it all and its going to eat her alive if she doesnt let go. And claims the love we had is gone. Which was the truth? How she was in person and the things she said, vs when im gone again to allow us to grow when she sent that message and blocked me? Is she telling the truth or trying to protect herself out of fear of getting hurt?
