Alright just fact-checking some stuff said here:
You don't have to break up with Eric before Somalia to get a relationship with Alpha Eric, although it IS the simplest way of doing it. To get Alpha Eric without breaking up with him early you need to not select the red options when having cam sessions with him (to avoid turning him into a cuck) and you need to not "cheat" on him.
What counts as "cheating" changes depending on your status with him, if you said you were going to wait for him you need to avoid pretty much all sexual content and stay loyal until he is assumed dead, if you said you wanted an open relationship you need to avoid SOME arbitrary sexual content (Don't go out with Doug, don't do the scene where Ash sucks off Jasmin on the massage table, you can do the Wilson scenes but make sure Ash is not into it, don't have Arthur be your sugardaddy, maybe a few more I'm forgetting)
To keep your job on Ryan's company you either need to keep the good outfit and NOT go on the trip with him (it is okay to refuse going on the trip, but you will be fired if you agree to going and then reject his advances during the trip), or you can go on the trip and become his office slut for the rest of the game, note you can't be his office slut for the rest of the game if you choose to commit to a relationship, so you will get fired if you do that.
