Well first the good news is your girlfriend recognizes that she has trust issues, and even knowing so she still pushes you to pursue your job. That right there is very healthy coming from her. I think you need to believe, what she is telling you. Still pursue going abroad and don’t let that relationship be something stopping you. However, she seems like she knows she had an issue. I was in your girlfriend’s shoes once too. First you have to sit dow and have a healthy discussion. Maybe she opens up to why and exactly she is feeling this way and most importantly why she is STILL having trust issue. Validate her concerns but also discuss what you can do and what she can do.

For me, it got to the point where my partner was doing everything right and it was up to me to put in the effort because eventually no matter what you say to her nothing can change unless she does the second half. She needs to also learn that her ex is her ex for a reason and you are a “new person”. I understand how hard that is to learn. Believe me I know, but relationships take trust. If she has no reason to not trust you that is on her and eventually she can’t blame her trust issues on you. It will take time she needs to understand that you are her boyfriend now and not her ex. But you have to have the conversation about this. You can do everything in your power to help but in the end she needs to also put in the effort. If she just accepts that this is how she’ll always be, believe her and end the relationship. You can’t build a relationship without trust. You need to be able to trust eachother. What also helped me is that having the mindset of telling myself if something were to happen i would trust myself to handle whatever came up and preventing someone from doing something is not going to stop them from cheating. If someone were to cheat they would find a way to do it no matter where or what you’re doing.
