Long distance

This is an invitation for advice on my situation from any perspective. My girlfriend and I are 21 and 19 respectively. We just passed 4 months in our relationship and have already had some serious issues, but we have always worked through it. Her previous relationship was an engagement and she was very close to his family. It seems that she wants to stay close to his family and even get support from them more than her own. We have had to start a long distance relationship due to me losing my job and her still having hers. She recently suggested moving into her ex's parents house while she pays off her bills and doesn't understand why I'm livid over the idea of her being so close to them. The other thing is that they are the managers at her current place of employment. She's scared to move on from that job, which is understandable, but she also is expecting me to relocate when i have the money back to the small town she lives in and try and find a job there. I'm confused about what to do. My dad is close to me here and has offered to help us both out if she wants to move here and try and get started on a more permanent life together. But in her eyes my family helping isn't an option. It really hurts that her ex's family is an ok option for support but mine isn't. Just looking for advice.

There is something seriously wrong with her. Those people are his parents not hers. When she left that relationship she left the parents too.

You have only been in the relationship for 4 months. There will be more of this nonsense the longer you stay.

I think 4 months is too early to have issues like this in a relationship

she still loves that other guy.

sorry, i doubt that's what you wanted to hear.
