AITAH for not feeling devastated after my gf(18/19f) just dumped me?

So I(19m) just got dumped by my then girlfriend, now ex(18/19f). First of all I just wanted to say I really was into her, I really liked her and I don't know if I will ever feel like dating again after her because I don't know if I'll find anyone I like more than her when it comes to looks, this is a long story, I obviously care about personality too but this is a seperate story. Anyways, our relationship lasted about a month, we where going strong the first 2 weeks, just for a note we are long distance, she's from Russia and speaks only Russian, I'm from america and speak both.

Anyways things began getting weird after 2 weeks in, she normally posts on her telegram stories every other day or sometimes daily, I began to notice nothing was showing up, on top of that there where certain days she wouldn't text at all, sometimes 2+ days, anyways about a week ago I was concerned about her and I redownloaded the dating app we met on even though she told me to delete it, and it shows she was like recently active, this was kinda red flag 1 and I ask her why she was ignoring me to which she said "she's always working".

Now more recently like a few days ago, there's still been no telegram story.... On top of that 3-4 days ago she said it was her birthday, nothing weird about that, right? Well we'll get to that later, anyways after the day she said was her "birthday" she vanished for another 2 days with no texts, then some gut wrenching feeling kicks in me and tells me to check my telegram account on my old phone that she doesn't know of and I looked her up and yeah.... She had stories every other day mostly every day going back to the day she hid them, and her birthday? Nothing usual for birthday activities, nothing at all, and her stories where all of her just doing normal activities like with friends or watching TV, ect, I'm not opposed to any of it at all, I just find it weird you use "work" as an excuse to not send a single text in over 2 days and hide your telegram stories while also posting about just general stuff, also I checked back in on the dating app and looked at her profile to find her zodiac sign isn't what lines up for what she said her birthday is which is extra suspicious.

Thursday night when I figured this all out I kinda just used as my day to wheep and you know, as that's the day I found this all out, anyways we come to yesterday and I sent her a message that says something like but not exactly: hey, let's get through this okay? Unhide the stories you have and please give me full honesty and in return I'll give you my full patience, anyways this morning I got a text saying exactly this in translated form: "Sorry, I can't be with you. You're making too much up and I don't have time for a relationship."

I read this when I was half sleep and didn't respond, today when I told friends about my relationship being over but also saying I felt weirdly calm or at peace with this, they said I must have never really liked her and that I am an asshole, I don't know, am I the asshole for really not caring or being at peace with her breaking up with me despite me liking her?

Note: this is probably the last time I'll ever date again, i don't want an American woman or really anyone from any other country for reasons I won't disclose but I don't know, I feel as if this is kind of the end of the road for my love life because this is not the first time something like this has happened to me before and I don't think I can really ever trust someone again nor be attracted to someone as much as I was attracted to and loved her.
