“Was he in depression?”

I thought I had a person for Valentine (learning experience)

We are in our early 60′s. His hot temper / stubbornness caused a lot of problems in the relationship including broken engagement, but we always celebrated the 14th. I just found out he did not even realize the arrival of this year’s V day. Was he in depression? Because he could not lose the 60 pounds he gained in 3 years, the weight starting to affect his health, or a signal for me to move on while I am still trim, fit and youthful looking?
