I've been best friends with somebody, we'll call him E, online for about 4 years. He has an online GF, R, who he has met IRL probably once a year that he has been dating since high school.

Me and E are best friends. Like, legit. E also knows I have pretty much had a lowkey crush on him the entire time I have known him. It's NBD; I'm in a lovely relationship ATM and never pressured him into being with me. We playfully flirt often in a friend way but both understand we are each in a relationship.

Yesterday, I told him he needed to break up with R. He is about to finish college and move across the country to live with her. I am 99% sure she is emotionally abusive.

I typed that out, with reasonings to this conclusion (tldr; guilt trips, victimizes herself constantly, expects his time on a whim, makes him walk on eggshells, etc), apologies for saying it so bluntly, and empathizing a lot, as I have been in a handful of abusive relationships.

I know he would not be safe or happy living with her and this is only his second relationship ever. But - he knows I am and always will be kinda into him. I hesitated to say anything but he implied last night he was going to propose to her. I genuinely fear for his well being - and I have tried telling him this just short of literally BREAK UP WITH HER.

Sorry if this sounds like seeking validation; I know abuse needs to be stopped and intervened, but was I too blunt? He had not responded since I send the message last night. AITA for being so blunt (or for taking so long to finally say anything?)
