Hello @samaabdeltawab. I read your post thoughfully. You reiterate several items you have doubts about. While it is true that no one knows what will happen long term, following your gut instinct when you feel something is not right should not be ignored. Only you know the reason why you have the feelings of doubt. No one else outside the relationship can tell you what is the right path for you to take.
You must examine each question you have in your mind that gives you doubt and work them out to find out the underlying reason.
Thanks for sharing and take care. I sincerely hope things work out for you in the future.
Take care.
