I ' m really sorry to hear about everything . I think your ethic and outlook is something to applaud you on and don ' t stop for anyone . This was lengthy to read and I may have forgotten details but I really think that your friend lost interest in the idea and plan and didn ' t know how to tell you he wasn ' t into it 100 %. This drove a wedge between you two and I think he feels bad about knowing you have cancer . It can be difficult to deal with knowing a close friend is going through something like that . All this pressure may have overwhelmed him and he just cracked . I ' m sure he cares about you . I just think he feels like this is all too much and I encourage you to talk to him again and say that you will not pressure him and want to focus on the friendship and not the business . Maybe then he ' ll feel less overwhelmed with everything . Do you have other friends that you can consider building a strong friendship with ? Maybe pursue the friends you already have to tighten the bonds .
