absent dad

Briana
So my parents divorced when i was 9, my dad used to pick me up on weekends which then turned to wednesdays which then turned to every now and then which eventually turned to nothing. I would go weeks with out seeing him and he could care less. I am now 26 years and things are still the same. 
   I gave him a chance and was seeing him about every two weeks which was nice. I got engaged and didnt hear from him for two years and a year after my wedding. I would send him pictures, call him and text and no response. I invited him to my shower for my son and no response. I gave birth to my baby boy and he showed up to the hospital, i was furious but didnt have the guts or heart to tell him off and with that he was flirting with my bestfriend and he is married. 
Since then, he tried to come over once and i said no. I am still hurt but when i sent him pictures of the baby he did not respond. In a way i feel like i shouldnt have pushed him away but i honestly am not ready and i am unsure if i even want a relationship with him anymore. I know he is a jerk but he is my dad and i love him but i am tired of being hurt. Should i let it be or keep trying?
