Re: Big dilemma!
Have you ever met him in person or just spoken over the phone? Before making such a HUGE decision, it might be a good idea to meet with him and spend some days together, so you guys can see in person how you hit it off. He might be shy and distant over the phone but when you meet in person, it might give you a better indication of his personality. See how he interacts with you, with his family, with your family, with his friends etc. Also you can ask his siblings and friends about his behavior, maybe it is normal for him (some ppl r very quiet and shy) or maybe he is just going through a tough time in his life or something and you might be able to help
Hope it works out for you and that you find happiness and love in your life
