I just broke up with my 6-year crush who became my bf last year

The man is bisexual who goes to church. Had a crush on him for 6 whole years. We have been best friends for about 7 years or so.I had a huge accident last year and somehow I was so brave to tell him I love him so much. He accepted with some hesitation and we started dating like a couple.Now a lady from a church got herself into the relationship and somehow located my contacts. 3 weeks ago, she told me to leave my love and never contact him again.Long story short, they formed a new relationship last week and even went to camping together. Meanwhile, my love remains uncertain, he told me that we can still be friends like the old days but I just cant......Since the day they went camping, I have been so drunk and sad that I wanna hide from everyone.What can I do now... I don't wanna admit that the relationship is over but the reality says the otherwise...
