I wouldn't get my hopes up, because it never works out. Well, almost.
Let me tell you a story.
1st year of college. There was this guy in my German class. We became friends, but I soon realized I had a crush on him. I knew he was straight, but being 18years old you still believe that miracles can happen so I kept on dreaming. Every time he smiled at me or said something nice I felt like 'Oh my God, maybe he's gay?', but I never got the courage to even ask him out because of my insecurities. 6 months in and he had to move to the UK. I felt horrible at that time, but I didn't want to make a fool of myself so I just let things go... Then one day, 2-3 months ago, I was browsing through gaydar.co.uk and guess what happened? I stumbled upon his profile. Thought I was gonna pass out when I saw his pics. I immediately sent him a message and he replied withing seconds. He seemed just as shocked as I was. We talked a lot and he told me he was attracted to me ever since he saw me for the first time. It was just insane, because I felt the same way about him. None of us got the courage to do sth about it and now it was too late. He already had a boyfriend and I was dating someone else. Still, that was a bit of a downer, but most of all, an eye opener. Now when I think some guy might be gay and we get along well, I just ask him. You never know what may happen... Just saying.
