Phone Drama?

Ah, this has been a crazy adventure since my last post. I stuck by my word and kept SD's entire area code blocked from my phone. However, the app does have two methods of which it blocks calls; The first being answer and hang up automatically, the second sends it straight to voicemail. I was curious to see if he'd call, so I set it to send calls to voicemail because he always leaves a voicemail, even though the app does tell me if a call was blocked. SD has been blocked from calling since October 11th, and has not attempted to call once. But for some reason, I lost my gut and opened the door back up.
Thursday night (October 18th), I decided that I wanted to see if SD wanted to see AK or not Friday when I brought him down. So I asked SD's mother for his phone number, she gave me the home phone number for the residence of him, IB, and IB's mother of whom SD and IB live with. I called, no answer, and I needed to inform my friend of whom we were riding with to save gas of whether or not I'd be going for sure (I had a lot of things going on and was not planning to go unless he wanted to see AK) by 8PM, and it was now 6PM. So I called SD's mother back and asked for IB's cell phone number, since SD destroyed his. This, ladies, is where things get 'fun'.
I call the phone, and IB answers. I politely asked "May I speak to SD?" She nearly broke my phone with the attitude she popped, asking "Who is this." I told her who, and she hands him the phone. I assume I'm on speaker because of the echo, which I usually am. SD answers while I hear IB in the background screaming "Ask her how the hell she got my fucking phone number", when maybe 3 weeks ago she was saying 'OMG let's be BFFs'? He asks, I tell him that I asked his mother for it because I needed to speak with him immediately and she was only being polite, he does not repeat what I said (Furthering my suspicion of being on speaker) when I hear IB say "Oh hell no, I'm going to call your mother and cuss her ass out, blah blah blah" (After ass, I tuned her out). That's when I heard it.
"Shut. The. Fuck. Up." I'm stunned. This is the same man who called this woman his sun, moon, and stars...Telling her to STFU? LOL! I laughed so hard, I couldn't resist it. And it made it even better when I hear her say "Oh hell no, you ain't gonna talk to me like that". He replies with "I'm so fucking tired of hearing you bitch." Oh my god, by this point ladies, I'd soaked my panties with just the venom he was spewing to this person who he admitted on multiple occasions was more important than his own child. She storms out, we have a conversation and I tell him that I'll call back in an hour after he figures out whether or not he can find a ride to the location. This, again, is where things get fun.
I call him back in a little over an hour, and IB answers again with the same amount of attitude, and I politely ask again to speak to SD. I hear her scream "God damn it!" and put SD on the phone. I'd had just about enough of her mouth, so before he even speaks, I said "Put her back on the phone." He nearly begged me, saying "I don't want to deal with it..." I said "Put her on the phone." IB is in the background (Again, I'm on speaker) saying "I don't want to talk to her." Too bad sugar, because that's when I said "Bitch pick up the fucking phone."
This time, she sounds like a shy little 6 year old girl when she answers, with a simple "H...Hello?" I asked her "Do you have a problem with me, IB?"
"Wh...What do you mean by that?"
"Well it would seem that the first time I called, you acted like a fucking twat. And don't think I didn't hear you scream 'God damn it' the second time I called which is really fucking weird considering two, three weeks ago you were saying we should be friends. So, IB, do you or do you not have a fucking problem with me?"
"Well...No that's not it. I just don't like people giving out my number like that."
"Get over it. He's the father of my son, I needed to speak with him immediately."
"Well...I guess you can call this number ONLY if it's an emergency and ONLY if you can't get us on the home phone."
"Hmm...Yeah no. If I need to speak with him, I will call your phone, your house phone, your mothers phone, your aunts phone...Get my drift? I will call whoever, whenever I want if I need to speak with him. Got it?"
"Here's SD."
"So glad we got that taken care of, you have a great night sweety."

So funny...It really is. It's hilarious when someone has all these balls when they're not speaking directly to you. Mamas, stand. Your. Ground. Do not let the new girlfriend, if she is anything like IB, treat you like you're not important. You gave birth to that child, you have raised that child, and I don't care if it's just to call and say "I farted and it stinks", that is your right to do so. You have the right to be in contact with your child's father and don't let girls like this make you think otherwise.
