Dealing with no contact

Mom unfortunately left with our daughter while I was at work.. I had no idea she felt a certain way since days before we were at Sea World and the Zoo. I felt like we were enjoying being a family but she felt differently inside. She disappeared with our daughter and it’s been almost 2 months now. About 2 weeks ago we finally got into contact with eachother. We both seemed to want to get back together and she claimed she missed living with me as she’s now staying at her parents. We would talk for hours a day and talking to my daughter was great, we had a discussion she was going to tell her parents about having her come to bring me our daughter to be able to spend time together. She tried to tell me too “I left the house but we’re not broken up I just was overwhelmed as a mom and felt like I wasn’t ever enough for you”… I’d do anything to keep my family together and be there for both of them. When she told me this one night next morning she was going to tell her parents about me cause she loves me and that she wants to come see me with our Daughter. Well, that whole day she didn’t answer the regular good morning have a great day text and I was concerned so texted her again if everything was okay. All I got was a we need to talk when you’re home. Called her as I got home and I got the “we can’t do this anymore I can’t do it “ and it was very confusing to me. I feel at this point her parents are controlling what she does with her life and I can’t intervene there as her dad has made threats to me countless of times and so has mom. I filed for custody/visitation the next day over they disappeared but since I had no ideas of her whereabouts I couldn’t serve her. When we started talking again she was clear on what she wanted so I never bother to serve her. I don’t know if it was wrongg for me but I ended up having her served the next day over that she gave me that “I can’t do this anymore”. She reached out to me saying I made everything worst and now I created more problems. My only intention was to be able to see our baby. She has now sent threats to my parents what will happen to me obviously if I follow thru with tryna get custody/visitation regarding my legal status. I’m here legally on a work permit and she’s treathening she’ll have ICE come to my home,my parents are both citizens so I’m afraid of anything affecting me or them as they had a long process years ago to become citizens. Now I feel like my only choice is to dismiss the paperwork I filed in the court and I let her know I would. I still haven’t been able to receive any answer or any communication about our baby and if I’m able to see her any form of way even if she doesn’t want to see me. But she’s not willing to cooperate or communicate at all now and I feel her and her parents have me by a hook and I don’t know how to cope not being able to know anything or even know when I’ll be able to see our baby again. Am I doing wrong
