Not "just" friends
has a section on the timeline. Unfortunately I was so desperate to know it all that I wrote the timeline with him telling me details. This is not how it's supposed to be done but I was desperate to know everything ASAP.
Mine is several pages long and was an evolving thing. It started with the first sexting that I could document from his yahoo chat account. Very little space between those. They were simply the username and date. Then a few spaces in case I wanted to add some note later.
Once we hit an IRL AP I used a full sheet (and two sheets for the last MOW) for the ones that weren't ONS because I can add more notes as I found out more and then I could refer back to them when any new info came up and see if he was lying or trying to change his story. (He didn't but it was important to me to have this ability).
Separately from the timeline I have any emails/chats/etc that provide details of the A's themselves. For example I have recovered some emails between him and AP#1, AP#2, a woman he was trying to start something with but it didn't go farther then a few emails introducing them to each other, and emails from AP#8. I have facebook chat logs from AP#8. I have an email confirming AP#8 and his hotel reservations on OUR anniversary. Etc, etc. Oh, and any emails/text logs from correspondence that I have had with any of the AP's or potential AP's.
I also have several copies of all this information. I have copies on the computer but also paper copies hidden as well. I never want there to be a point where I don't have the evidence to prove all he did.
At some point I know it is unhealthy to keep this stuff but for now I don't look at it but I am NOT ready to destroy it.
If you have any other questions feel free to pm me and I will explain further. The biggest thing is for the timeline to be in a format that you can easily and fully understand what happened to you during your WS's A or A's. It is important that you get all the information that YOU want out of this time period and that is the goal of the timeline.
