I Don't Have Many Good Memories of My Father

I have no relationship with my father...he left when I Was six...he told me he was just going to do a job...then he left and only came back every other day. Those visits became weekly, then every other week, then every month, then every other month...then I didn't hear from him for 4 years...until now...when he calls me up saying he's "sorry" and "he want's to be a real father to me and my little brother." He's married to another woman now...and has another kid...a daughter now...and he wants me to go meet him at a freaking McDonalds after 4 YEARS of nothing. No phone call when I was in the hospital and thought I was going to die. No "happy birthday" no "merry Christmas". Nothing at all. Then he calls me trying to get himself back into my life...but I can't...would any of you want him back in your life? After he abandoned you? After he lied and disappeared off the map. And then comes back to say, "Hey it's your dad. I'm married to someone else. And I have another child now. Want to meet at the nearest McDonalds?" I don't think so...I know I don't want him barging into my life and messing my life all up again...right when things get in order...kind of...my life is falling apart...so, when will things go my way?
