We all have experienced the feeling of being "alone" in a room, but it takes time to get over that. You are still very new to this game called "MLC". One of the things that helped me overcome this feeling is that I learned to say over and over again, I am just as good as the rest of the people in this room and I have a lot to offer. I learned to put a smile on my face even when I was feeling sad and I "forced" myself to introduce myself to others and beat up conversations w/them. It's a huge step, but it was what I needed to do to get to the other side and learn to chat up people in my "single" state.
You will need to find projects or start some hobbies so that his "alone" time in his room doesn't disturb you as much. You need to learn not to depend on him to keep you company...this is your time to learn about yourself. Make a list of the things that you want to do, i.e., learn or complete and get started on them. You will find that the hobbies and projects will open doors for you to meet new people.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
