Post breakup scares

We broke up, he continued to lie to me, and I'm just done. Now he comes back crying please please please give me another chance I realize everything. I don't trust him at all so deep down I know we don't need to be together, but god I love that boy more than life itself! I will do anything for him.I don't know if in afraid to be alone, or without him. He calls me and texts me. Woke up to good morning beautiful I love you . And it breaks my heart because I just want to be cuddled up next to him. What do I do y'all
