Hey milk it's me mocha! I've missed you so much it hurts. I love you. This was the words from a GIF my boyfriend sent me 7 days before he died?

When I received it that day, I didn't think anything of it. He was home and hadn't been gone and I hadn't gone anywhere. After he died suddenly in September, I read it again. But I just don't understand what he means by what he wrote. Anyone know?( And don't say "Why don't you ask him"? He died ok).

Milk and Mocha are a couple on GIF's you send to people to their text messages. Milk is the girl, Mocha is the boy. The GIF shows the boy maying on his back and she is licking him (they are 🐻 bears) to make him feel better after what he said to her. We used to send them back and forth to each other all the time.
