Moving abroad after marriage?

I am 27F was looking for a partner. Met this guy on JS and we talked. After talking with him from 2-3 weeks I have realised that he is the person that I wanted to have as a partner. Everything was perfect until we discussed about our future plans. He is living abroad and l am living in India. I never imagined my life out side of India. Never thought of settling or moving abroad after marriage. I asked him if we can settle here in India but of course career wise it’s not easy for him to comeback here at this point. So he agreed about coming back and settling here somewhere in near future. But now I am confused whether I want to leave everything behind, my family, my friends and living abroad for 10-15 years and then come back to india to settled up. Because I never imagined this life and I am not sure how well I will do in career there. How well I will cope up with the surroundings and having fewer Indian friends there. I am attached to my family. I want to be here for my parents in their old age. Tbh I am kinda scared to start everything from the scratch away from my loved ones. But that guy is everything that I can ask for. The partner that I wanted to have. I like him alot and he is also very much into me. I’d appreciate hearing your thoug
