Me (26F) and my boyfriend (27M) have been in long distance relationship for 4 years. Before relationship we have been best friends for 5 years. It's a perfect relationship and works for both of us. He is a great guy and loves me alot. We both planned on getting married once we have a surety on career side. But so far we both are just doing fine and not really have established a well to do career so far, and since we both are at marriage age and he wants me to spend his life with me, he asked me to marry. Although I love him dearly and have no feelings for anyone else, I am still having doubts. I just don't understand why. Maybe I care too much about my career right now or not really mentally prepared. What should I do in this situation?
