Another Change ...... Dilemma

Hello, I want to share my story. I am 25 years old. The last year has been very difficult for me. I had a very orderly life - a long relationship, many years of work in a good position and a good salary (excluding the extremely heavy workload and mental harassment imposed by the employer), but at one point both were exhausted and I had the feeling that I was not moving forward one place. I swallowed many things, I kept silent many times. I want a change! And here a year later I have a new job (twice lower salary, but at least they treat me like a person) and a new relationship (with a very good person, but I'm not sure what plans he has for us) . In the meantime, I had a lot of problems with my ex, he was harassing me constantly, I also had a lot of problems with my ex-boss when I wanted to leave. All this ruined me mentally. I wondered many times if I had not chosen the wrong path and if I had not made a mistake! At one point, I wanted a little peace of mind to decide what to do with my life and try to put it in order. I wouldn't say that I've arranged everything, but at the moment a new opportunity opens up before me and I don't know what to do. Should I take the risk again (or would I be wrong again if I do). I am offered a responsible management position in an office opened in my city where I will work alone, but before that I have to undergo training for several months with a salary like in the current job, but in a foreign city. The proposal comes from my relatives. What they could teach me, no one in the industry would hire to do and give their craft. In this case, there are pros and cons. I've been thinking about it for a week now and I don't know what answer to give! Should I make another change in my life Will it be for good? Will I not regret it after that? Won't I make a mistake? I wonder what advice you would give me .....
