I met one friend approx 10 month ago. Friendship is started from my side. When i started friedship he was heart broken and he had break up with his gf. At that time i thought that i have to support him in his pain. Then i talked to him like everyday. Then after 6 months he was recover from his break up and want to find a partner for him. He created accounts on dating apps. In that he found one girl and he likes her very much. He shares this things with me that he likes that girl so much. I said ok then spend time with her to know her and get married to her if she is agreed. After that i am not used to talk to him everyday because i think i am disturbing them. I stealing her time from him so,i quit talking to him. I think that as a friend my duty is over so, i have to leave him with his girlfriend. Dont know how in that months in supporting him i made one mistake and fallen in one sided love with him. I regret that but i cannot controll my feelings at that time. What should i do i hve to leave him with his girlfriend or i have to behave like a normal friend in front of him. Beacase on one side i am happy that he found his match but on other side it is painful for me to hide my feelings.
