I’m 24 and she took my kids

Hey guys I’m kinda just looking for advice, i just got out of the Marine Corps and I was supporting my wife and two kids. I was working everyday and doing odd jobs on the weekends. We lasted for 2 months post EAS. She told me she was going home ,which is half of the country away, for her birthday. After a week she wasn’t texting or calling me back, and she texted me and said “I’m not coming back, give me space” she always complained about me not being there idk what else I could do. I’m so hurt and alone. I’m just lost and in need of advice, I’m at a very low place in my life right now.
