I don't want to give up!

[LJay]

Don't show up at his workplace. Mixing personal problems with work is often very hard on all of the people involved. It can also present your friend in an awkward way to his supervisors and coworkers.

If you want to do flowers, have them delivered by a decent florist--along with the can of Monster--to his home at a time when you are pretty sure he will be there or that someone will be there to receive them. You can attach a card that says "Missing you--Would love to touch base." or something of the sort. Make it a simple bouquet and not too showy. The florist can help you with that.

Then prepare yourself to get an answer, or not. He may be ghosting you. He may have problems completely unrelated to you. He may ...whatever. You simply have to toss the ball into his court and stand back for his reply. In other words, give him an opportunity but also give him space.
