The scene was very well set, as were the characters who are strong but have different personalities. It's probably those differences that drew them together and strengthens their friendship until the bombshell dropped. Adam's reaction is understandable considering his upbringing by a preacher and his wife, although that does not make it right. Naturally, Luke is hurt and understandably so. Reading between the lines I'd say that Luke hoped their friendship was strong enough to overcome this difference too, but feared that it wasn't. Luke's hurt shows, hence his tears, but he regains his strength and holds out hope that the friendship can be saved and I hope that he is right. I applaud the bravery in sending the text, he's fighting for the friendship letting Luke know that it means something and important. It is my hope that Luke realises that and that his response is a positive one. I know what want that last message to be.
You drew me in and I could feel the friendship. You told me a good story that held my interest, I was enjoying it until you dropped the bombshell and I read the end through tears. How could you end on such a cliffhanger? Not really, I enjoyed it from start to finish. The ending is nicely done leaving it all in the reader's mind as you left us to end the story in our own way. I know how I want it to end and would love to see a follow-up.
Okay, some have said that there are some writing and grammatical errors, so what, it is still a good story and they did not detract from that. None of us authors are perfect, my own stories prove that I'm not, but we can all improve given time and some good help. You show good talent, please continue to write and share that talent.
