Wife Wants To Leave The Us With 2 Year Old Daughter

Hi guys, throwaway account for privacy reasons.

I 29M, have a wife 28F who moved to the US (Connecticut) on a K1 fiancee visa from Mexico. We have been together here for 3 years, and known each other for 5 years, and from my perspective pretty happily. Of course there are occasional arguments, but I feel like we've always resolved problems pretty healthily without involving others, raising our voices, or saying hurtful things to one another. We have a very healthy sex life, and go out on dates/family outings very frequently. She does little things, paints for me, gives massages, I buy her flowers every other week, etc. Just to say that it feels healthy, more so than any relationship I've experienced. We have a 2.5 year old daughter together whom I love more than anything and would do anything for. She is smart, athletic, and a wonderful kid. I never thought I would have children before this relationship, but it has been the most incredible, rewarding experience of my life. If you have gets you understand what I'm saying, if not - it's crazy. So many things in my life felt important before, but this puts everything into perspective, and really my primary motivators in life now are the happiness and security of our family.

I am the primary financial provider of our family, and also do most of the cooking/cleaning/yard work - not all, but probably 75-80%. She works teaching dance classes, and brand marketing on her social media accounts as an influencer, and takes on the majority share of childcare when I am at work/my family isn't available to help. I consider all finances shared, we discuss large purchases together, but I trust her completely and we've never had issues with spending or 'controlling' what money is spent on. I feel like finances have never been a big issue, which is why I'm so blindsided by this.

Recently, my wife has starting talking about a past fling she had with a very famous musician (going to leave out names due to privacy, but think billions of streams on Spotify, very well known in their genre) everything between them happened before we met, I know they spoke and saw each other once before she moved to the US and we married each other but as far as I know, that was the end. I know he offered to pay for her to move to Europe, and she rejected his offer. I have complete trust that she's telling the truth about that and nothing else happened.

She talked about it more and more, with the tone of the talks being about how she regrets not choosing that life, and what life would be like if she hadn't come here. She's made comments about how she envisioned bigger things in life - always traveling, fancy excursions, on private jets, etc. I was really taken aback, because while we are not wealthy by any means, I make mid $100,000s yearly and feel like we have a comfortable life. I have a fantastic work life balance and can spend time with my family.

I wasn't really sure how to respond, but tried to just show her love, and said that I understood that sometimes the grass just seems greener, but that our life is continuously growing and improving, and I'll always support her and look to make some lifestyle changes if she doesn't feel happy.

These talks basically went nowhere, and she cried and just compared me to this guy. Said that I stole her life away and that she'd never get to experience the life she deserved. This really hurt me, because she initiated the relationship, and we were both madly in love , traveling monthly to see each other and planning a life together. I never felt like I was coercing her in the slightest, she was a bit hesistant/scared to come to the US at first, but felt better after i helped her become comfortable with the language. She wanted to have a baby, and I feel like I've been very supportive with her career.

Well it all seems to have culminated with her telling me that she has already talked to a friend in Germany, who will let her live with her for the next few months, has reached out to the famous guy who has said he's interested in seeing her again, and that she will be taking our daughter with her. She apologized, and said that I am welcome to visit anytime I want and she will try to video call me so that I can see my daughter, but basically that she just knew her worth and deserved someone better than me

I am at a complete loss of words, about to fall into a depression and I honestly have no idea what to do. Can she do this? I know she has very little income, or stability - can she just pick up and take our daughter to the other side of the world to be with some other man no questions asked? I'm scared, I feel like the last 5 years of my life are a lie, it's like some kind of nightmare turned true.
