cheated on, lied to, and now I am moving on

Well, H picked up S today (surprised he remembered since there has been no contact from him). H acted completely normal. He acted like nothing at all had happened. He even tried to give me a hug so I did a half thing, but that was it. I was curtious and mostly focused on S, what he needed, and what we are working on right now so H can continue it.

Then when I picked up he conveniently asked about the postcard... Here is pretty much how the conversation went...

H: what were you talking about when you said a postcard?
Me: a postcard from your travel agent came addressed to you and OW
H: I don't know why I haven't gone anywhere
Me: It was addressed to you and OW thanking you for your travel arrangments
H: All I can think is that OW used my credit card to pay for a plane ticket to see her sister graduate because she didn't have room on her's. What did you do with it?
Me: Threw it away
H: was it from (insert travel agency here) because maybe OW used them to get the ticket
Me: (nothing said and just kept getting S into the car)

He was just so smooth with the whole thing and had an explanation all ready like always. For a little bit tonight I 2nd guessed going to the L because this is it, but although this nagging feeling keeps coming, I know that he is lying, and even if his story was true, why is he letting her borrow his credit card when he wouldn't let our mutual friends borrow movies. Plus that still effects me because if something happens I am liable for that debt. I am not paying for anything for her. However I know it was a lie to cover his butt because that is what he does, and he knows I have no way of knowing what actually happened.

Plus he hasn't done anything for months to work on us, many of my friends see them together around town driving, and he said he wanted a D, but didn't have the money yet (which is stupid because he should have $3000 from our savings left). Either way it is time to be done. I just don't know when I should tell him I am filing. Do I tell him at all or just have him be served? What is the protocol?

S acted up because he didn't want to leave his daddy since he only sees him twice a month, Fridays for 3 hours and Saturdays for 10 hours. It is hard on him because he wanted to see his daddy this week, but H never answered.

Oh well...now off to bed. Any advice is greatly appreciated because I am floundering a bit although I know in my head I have to do this. I am just so scared it is the wrong decision...much like the night before my wedding when I had the thought of the anonymous letter going through my head (the letter was saying how H was sleeping with this red head. How he would always love her and not me). Hard stuff so advice is welcome.
