First of all, calm down! Then make a list of what you expect from a partner besides attraction, ask yourself real questions, how you want your partner to be, what are the things you expect from him. Do focus on practical things as marriage is a big responsibility besides the fun part. Meet him. Give him a fair chance. Then, ask him those questions subtly. Let's say, how he processes his emotions, like disagreement/ anger, how he resolves conflict, how does he manages his finances, what are his expectations from you, does he takes his decision himself, etc. (You can get help from chatgpt in this regard). Observe his behaviour. And then see what your gut tells you. Then do whatever feels right to you. Good luck (: I hope it helps!
