It hurts

Adrians dad contacted me about a week ago telling me that he misses me again. I dont understand WHY he feels the need to tell me that. I told him that he needs to fix his marriage. But he told me that he really misses me and I havent hurt him as bad as his wife has. I dont understand. It makes me feel confused about everything. I want to be free of him telling me that he loves me and he misses me. Its been 3 years since he left. There is a sting when he says it. Id be lying if I didnt say I didnt love him but I do. He is my sons father. He was my first love. But I wont let him have control over me again. If he didnt have K, I would take him back. But he does have K and he is married to B. So.. I will never take him back. I am finally starting to be happy with myself.
