Okay, please forgive me if I'm being extra dumb right now (it's been a crazy week in the Deltra Quadrant), but I still can't figure out what Amber's trying to prove with these screenshots. I'll add img1481 from
@+who.cares+ here as a thumbnail so no one has to jump between pages to reference it:
It FEELS like Amber included this because it has a mention of someone being divorced, perhaps to convince us that Amber is thinking that "Erica" is divorced so therefore Amber's not a cheater. Amber's the blue bubble, and she's talking about talking to Erica all day, which is making the gray bubble person upset. As Amber is claiming to not have known Tommy yet, this would likely make the gray bubble person Alexis, and she's upset that Amber is ignoring her online bff of 13 or so months for the new potential gorlfriend. That would imply that the divorce statement would refer to Alexis (or whomever this is if it isn't Alexis). That would make this entire exchange irrelevent.
And if it's to prove the name "Erica", I'm sure that there were better messages to use over the YEAR that Amber would have been talking to Alexis about her that didn't involve confusing context. Also, that doesn't mean anything, because Amber has a long history of giving her girlfriends codenames and using those codenames in her phone and on social media. Amber showed her phone in 2017 where she had Becky programmed in it as "Greg". Amber would use Alex and Feline as codenames for Jade. And of course just over this last month Amber's been calling this mystery person Valentine and calling Emily "Tommy". Alexis doesn't have a codename, but that's because she really wants her name thrown into all of this and doesn't need one. Seriously, am I missing something here?
And I mentioned it a little in my last post, but image1483 is also confusing me:

"Erica's wife found out about me". Why would that matter? If I was talking to/seeing someone and found out they had a wife and were lying to me, I would break it off on the spot and immediately cut all contact. As in, blocked on everything - and I think that would be the most common and NORMAL response. Why would Amber be entertaining a call from this wife A WEEK LATER? Why would she worry that the supposedly cheating scumbag ex told her partner about you? I mean, it would be a simple response to the effect of "Your partner told me that she was single. I had no idea you even existed until 2 seconds before I dumped her ass and blocked her number - which is probably why she gave you my number to call me on your phone. You should take all of that up with her. Sorry that you're married to a cheater. Good luck. Byeee", if you didn't just immediately hang up and block the number. Is Amber trying some plausible deniability where she's trying to hint that she was aware of this woman, but thought that she was "Valentine's" ex or soon-to-be ex or something?
And of course, how does any of this disprove whether or not Amber knew about the existence of Colleen? Amber has a LONG history of keeping potential gorlfriends on the back burner while in relationships. She was working her dark magic on Krystle while still in a relationship with Casey, and broke it off with Casey and left the state within 24 hours of securing things with Krystle (the ONLY relationship where she wasn't' the dumpee). And although Amber initially said that she got the first DM from Jade 10 days after Becky dumped her, didn't she later hint that she and Jade had exchanged messages a year before but insisted that they were platonic in nature?
Even IF Valentine =/= Tommy (and honestly, I really don't care either way), that actually wouldn't mean anything. It could just as easily be explained as Amber messaging two potentials (at least - there could have been more that didn't pan out) and was waiting for something to open up. Perhaps Alexis wanted to set Ambo up with Tommy, but waited until Amber blubbered to her about breaking up with "Erica" before being able to push Tommy on her? Maybe "Erica" is real in the sense that she was an online friend, but Amber is leaving out key messages that change the context of her association with this person to pretend that there was a different girlfriend before Tommy? I don't know. With Amber, it could be anything, and that "anything" is ALWAYS sketchy.
Or does all of this just simplify to "Amber Lies", and I'm expecting 4-D Chess from someone playing Tic-Tac-Toe?
Edited to Add:
Forgot to mention three things. One, Destiny was engaged to another woman when Amber was dating her online. Two, Amber knew that Jade was Polyamorous when they first got together. And three, Amber has recently retconned the whole situation as being an "open relationship", but on askfm in 2014, Amber admitted that she cheated on Casey. Amber has a past of cheating; either being the one going out and cheating, or being the other woman while knowing she was the other woman. Any of these worst-case scenarios people are speculating could very well be the truth.
