another weekend without my son

Well i couldn't post yesterday so here is what happened then....
I talked to my son and he wants to come out to my house. so I told him I'd do my best to get a ride there to get him but that my car wasn't working. My ex got on the phone and I asked "how much money for gas would it take for you to drive him here?" her reply was "you know it ain't going to work like that."
So today...... my son is calling crying about how he misses his daddy and wants me to find a ride. I called a friend @5:30pm who was still at work. he's an hour away and has things to do before he could help. I called the ex back and told her what was up. she told me that was to bad because now she might not be around later. I said "i just want you to know what your doing to our son is wrong". and hung up. She called back and started b***hing, I said "this wasn't up for a debate". she was going "waaa waaa waaa" as i hung up again.
I called and talked to my son again.... he sounded so sad and in the back ground say "I'm not keeping you from your father". She's pinning the whole not seeing him on me. this sucks so freaking bad.
at 10:40pm i sent this message to the ex's phone:
Brian never called me back. I'll try to find a ride tomorow. what is the earlest you would be avalibe?
My ex called and said that she was planing on sleeping in. so I asked nicely could she called once they got up? she said yes.
My ex called back and asked "if your haveing such a problem picking him up How are you planing on getting him back?" I said "what? I don't know. You meen to tell me that you can't pick him up?" She said "it was a bad week and I cann't aford the gas"Me: "I told you that I would have given gas monie for both ways"Her: "hey you think I a B---h I'm going to show you what a bitch I can be"Me: "So your saing that since I can't asure you that I can get him back I can't have him?"Her "ya that about it"
So I now go with my 3rd weekend without my son. I hope she isn't expecting any kind jesters anythime soon!
