I'm closer to my mom because she's the one that raised me. My parents were never married and my interactions with my father were limited to holidays and summer in the earlier years, then, eventually, diminished to just text messages. Just recently, I decided to halt communication with him, because I was sick of the one-sided nature of them. Apparently, any strain in our relationship was my fault and, even though I surpassed him in education and even had a job that paid more than his, it never seemed to be enough for him. I've cried and beat myself (figuratively and literally) many times over this man. I'm 27 now and I'm tired of it, so I wipe my hands of him. My mom may not have been perfect, but at least she was there for me and was proud of my accomplishments while encouraging me to do better. She knew my father was a jerk off, but didn't want her feelings to influence my relationship with him which I greatly appreciate. She knows how I feel about him and respects my decision, even though she would like for me to keep a relationship with him since she never had one with her own father.
I love my mom very much and, as far as I'm concerned, I no longer have a father.
