Trust me, he hasn't forgotten you. He thinks about you a lot. His brain is scrambled right now and with the depression, it is hard for him to focus on more than one thing at a time. Also, they tend to compartmentalize stuff. Their focus right now is on making themselves feel better. They will try anything and everything to make themselves feel better.
You are probably feeling like he's forgotten you because he has not been in contact with you. They don't stay in contact. Some will pop out periodically, others daily and then there are some who disappear for days, weeks and even months at a time. When he does pop out again, treat him as you always do. Listen closely for he may tell you what has been happening with him during his "quiet" time.
Keep busy, read your bible and know that God has a special plan for the both of you. Dig deeper for patience and remember...you are on his time clock....which is extremely slow.
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.
