Sorry for your pain. It does not sound to me like you had much of a relationship anyway. If you are having major depression, then you need to take care of you. This may not be a good time to bring a bf into the picture.
Are you in therapy? It has helped me so much. I cannot say enough good about getting psychotherapy. Be easy with yourself. Don't put pressure on yourself. It is hard to make decisions when your thinking is not clear.
Time away from your bf is probably a good thing at this time. Personally, I believe before there can be a romance, there needs to be a friendship.
Give yourself a hug. You deserve it.
