What To Do About Dad

I just got off the phone with my mom, who is seriously worried about my dad. She said she just went to see the lawyer because my dad is in such a hurry to get the divorce done with. ((Sigh))
She thinks he has a girlfriend.
When I asked her why, she said she there was a strange car over there the other day when he wasn't home. And she found a necklace in their old bathroom. It had a 'K' on it. When she asked him about it, he said he had found it and was going to give it to her, meaning my mom. But why would he give my mom a necklace with a K on it?? Her name doesn't even HAVE a K in it.
When I asked her that she said, "I don't know Peyton, I can just tell he's hiding things from me. I also found a statement from one of our retirement funds that he forgot to mention, which has a lot of money in it! And if I hadn't found it and brought it to the lawyer, then I might be totally screwed out of that money!"

"Ok, well I don't think Dad is trying to screw you out of any money. He just...wouldn't do that. I'm not so sure about the girlfriend thing either. I mean, I know he's been going to see cover bands and he's always hanging out with these same 2 women, but...I just can't believe he already has a girlfriend. It's too soon!"

The thing is, my dad and I are now facebook friends. And lately I've been starting to wonder if friending him was a horrible idea. I keep seeing all these pictures of him out with different women, at bars, seeing concerts and stuff. And they all just look like floozies to me! I mean I've worked in bars for years, and I see the kind of 40-50-something single women that go out "to watch bands". They're mostly desperate, horny, gold diggers! And they're all trashy! And I don't think my dad should be hanging out with women like that!
So one these women he hangs out with happens to me named Kelly. WITH A K. And I do not like her. Why?? Well, for the obvious reasons of course. But there's more. One night, my dad posted a picture of 2 women (one of them was Kelly) making cheesy smiles, captioned, "Beautiful girls!"
And feeling, disgusted and angry I commented on it, "Eh, they're ok. What are they, like 25?"
My dad texted me the next morning explaining that he did not post the picture, the girls did. They apparently took his phone. I still can't decide if that's worse. But then I got a notification that Miss Kelly herself responded to my comment.
First my dad had written, "I'm sure they'll love that, about looking 25!"
And then Kelly writes, "Uh huh. I'm sure."

Uhh...wtf?? I know what I said was bitchy, but she fucking knows I'm his daughter. DO NOT FUCK WITH ME BITCH.

Maybe I'm being completely infantile, but that's how I feel. I am sooooo not ready to deal with my dad dating, let alone having a girlfriend!

I talked to Jenna on the phone yesterday, and she said she saw my dad at a family get together on the 4th, and that he kept talking to her about how he goes out all the time now and meets women, and she thought it was creepy hearing him talk about anyone other than my mom. ((Sigh)) Now I think I'm gonna have to have a talk with him. But what do I say?? I don't want to come off as judgmental, or accusatory, but...I'm seriously worried about him. I know my dad. He doesn't like to be alone. Not to mention he's a good looking guy. Especially for his age. You would never think he's in his early 50's. He doesn't look a day over 40! Both my parents look very young for their age actually, so I guess I have that to look forward to. But anyway! I'm afraid my dad is gonna take up with the first money-grubbing skeaze that gives him a compliment. And I definitely don't want that to happen. Part of me wishes I was still in Houston so I could really scope out this situation. I am going to be there next month. Maybe I can convince him to bring me out with his new "friends"...
