Foreigner relationships are a different ballgame. For example, don't mistake commitment to the relationship for commitment to you. The relationship may provide her certain tangible benefits (money, visa) that she is willing to drop everything in her life for. That is different from her being a unicorn willing to drop everything for the glory that is Newbie-Casanova.

If you think about it, it's kind of sus for anyone to drop everything in their life for someone. Pretty much no one is that special especially for an attractive woman who has many options. The simplest answer is she saw a path to something else and knew her abandoning career and family was only temporary.

These women may check certain redpill boxes like fucking you on the first date ('wow she must be creamin for me'), doing housework for you, sucking your dick on command whatever. But don't mistake these things for her traits as an LTR, she is a contestant on a game show trying to score your money or your passport.

So too this is why she makes excuses not to spend time with you, because she doesn't actually like you as much as you think and is trying to spend the minimum time possible to reach her goals. And, sensing weakness on your part, starts to make demands for her "security."

Consider it a lesson learned and a bullet dodged. I generally don't think these types of relationships are advisable unless you are old and just trying to have her pop out a kid or two before you die. That is, you are very aware of their transactional nature and are getting a bargain out of it.

I have been in search of a LTR to settle down with and have a family, not get married on paper of course. I am tired of having plates and casual meaningless sex, it makes life so mundane and insignificant. I want to build a legacy and have a traditional family. I am financially well, in-shape, and been on the search for a long time [emphasis added]

Actively looking for a relationship, especially an LTR, is a losing strategy for a man. As a man, your job is to get sex. A relationship is the woman's problem, and for you to grant or deny.

From HumanSockPuppet’s Guide to Managing Your Bitches:

A long-term relationship CANNOT be your end goal. You can only be OPEN to the possibility of having one.

Men are the gatekeepers of relationships. Since a relationship is what you have to offer, you mustn’t just give it away. It must be a reward she earns in small doses for inspiring your trust and devotion.

I understand that many of you want a LTR with a good girl – sometimes a series of flings isn’t enough to fulfill you. Believe me, I sympathize.

But winning a LTR is HER problem, not yours. Handing a girl your devotion won’t magically make her worthy of it. When you WANT a LTR too badly, you place your focus on the idea of having a relationship instead of evaluating the girl. You become fixated on your fantasy relationship and selectively ignore the things happening right in front of you: her deep character flaws, her indiscretions, and the red flags.

You must regard women as candidates applying for the job of being your girlfriend – a supporter, a lover, a comfort away from the everyday battles. Don't just hire a bitch because you want the position filled. Make sure you vet your candidates fiercely and hire the right girl for the job.

The 10+ years of MRP's existence have borne this out, and those guys are already married.

You're also most likely to find a relationship-worthy woman when you stop looking for one and just relax. I found my wife after I gave up on relationships and just concentrated on getting laid.

From your post:

The following is foundational. From Rollo Tomassi, There Is No "One". .

Should i even try to mend things anymore or is it better that i let this one go.

Also from Rollo: Rooting Through Garbage.

You have a lot of mental models you need to fix and/or replace.
