<human>: Can you condense the text into a few key points?

By give up, I mean cease all modes of communication. I don't have children yet, but even so, I can't imagine a parent ever giving up on a child. I would imagine that even if my child hated me, I would still send a letter or a card occasionally that simply said "I love you" so they would know I still care.

A little back story to the reason for asking the question. My parents divorced when I was young. A few years later, I moved with my mother to a different state. As per court order, I had 2 months visitation with my father during summers and he had every other holiday. 

When I would visit him, he didn't spend quality time with me, so I always asked to leave before the 2 months were up because I was lonely. He never asked for holiday visitation and denied all of my pleading for him to come visit me (The distance was ~900 miles). I never got letters or birthday cards. Eventually the phone calls slowed and finally stopped.

When I was a teenager, he stopped trying to contact me. The last time I saw him was over a decade ago, the last time we spoke was six yers ago. Recently, he contacted me via facebook and has been making excuses for why he stopped trying. Given past experience and disappointments, I'm hesitant to let him into my life. A lot has happened since we last spoke.

I apologize if this is the wrong place for this. I guess I want to know if I'm crazy in being hesitant to let him into my life again. I also think part of me would like to talk it out a little.
<bot>: Never had a great relationship with my father. After years of not speaking, he contacted me through facebook to try and patch things up. I'm a little weary. Could anything make you do this to your child?
