A couple of months ago I undertook a long term household project to build a large outdoor entertainment area including a deck, pergola and various other niceties. I did not have the all the skills necessary to complete this project all on my own, and had planned to contract out a professional to complete the project tasks that I was unable to.
During the course of the project I made a friend on an online community that possessed the skills required to finish the project, and very kindly offered to help me complete the project for free.
About a month or two ago, we were about half way through the project, but he became busy and had to work on other things. I shelved the project for a while, but a few unfortunate circumstances came up in my own life (financial concerns, time, and career-related duties), and it became clear that I was unable to complete the project. My best course of action, for myself, was to stop the project and sell off all the materials etc that I had acquired. This has now been done.
During this time, I had not spoken to my friend at all, as we were both busy with our lives but recently he has messaged me inquiring about the status of the project and offered to come and help me out again during his spare time.
Obviously, the project no longer exists, and I have not told him as such yet. I'd like to tell him that I've scrapped the project without offending him or have him thinking that I scrapped it because he stopped helping me or because I thought his work was not high quality (on the contrary), and basically tell him I was unable to continue the project due to my own circumstances. I'd also like to come across as thankful for his help and also offer my own help (as he is working on a similar project).
How can I get all of these thoughts into words?
EDIT based on comment:
- My friend did not help pay for any of the materials.
