21 year relationship ended two years ago, He was in a bad place due to his parents being ill, Stressed at work etc and he ended up depressed and on the verge of a breakdown. He left saying he couldn't handle being with someone at this point in his life and it would be for the best for us to split up as he couldn't give it his all.
We stayed in contact for a few months but I found it too hard, I still loved him so I ended up telling him I wanted no further contact, He respected it.
I contacted him when lockdown started to wish him and his family well, He replied saying it was good to hear my voice. We have spoke on the phone about once a week and we have been getting on like we used to do when we were together, laughing together, talking. I asked if he was still depressed and he said yes but he is getting there, has started to feel a bit better etc but still there in the background.
I still have feelings for him, I think because we didn't split up due to something bad like cheating etc I have found it hard to stop my feelings.
Do I tell him or just let things be?
