Give him time and space and he'll learn to trust you again. I'd allow him to make all the overtures except during training and heart-felt, genuine praise for doing whatever you ask of him until he's fully acting himself with you again. He might remember that in his mind you abandoned him, as dogs tend to think we cause everything that happens and right now, he's likely uncertain now to whom he should give his forever trust and loyalty. One day before too long if you bring him along with love and patience, you'll likely see the old him come out again when he's ready. Dogs rarely basically change their true nature but can hide it darn well should they feel the need. Now that you want him with you again, it's your job to help him feel safe and secure without overwhelming him. Just take it slow and allow him all the time he needs to show you he's still in there. He will.
