Happy birthday!! I hope you have a wonderful day. (or weekend)
And I just wanted to add my two cents...
He sounds alot like my dad. He would only show up when he felt like it. I would get all dressed up for him to come and get me, then I would wait by the window in the living room waiting for him to show up. I would wait there all day because I knew he would be there. Then, my mom would come in and say, "oh, sweetie, I'm so sorry, he called a little bit ago and said he wouldn't be able to make it. I'm sorry, I must have forgotten to tell you" I would be so angry at her. It wasn't for a couple years after that. (at this point he had stopped showing up all together) That I realized, he never called. That was the only way my mom could think of to spare my feelings. Honestly, as much as it hurts to this day. If he genuinely doesn't want to be in my life, its probably better for me in the long run that he wasn't in it at all. It was alot easier to know he wasn't going to be there at all, rather than not knowing if I was important enough only half the time. That would have driven me crazy.
