I'm no expert on relationships but it seems obvious that all good relationships are built on trust. In a love relationship each person must know that they can give their heart completely and won't be crushed and regret it. Speaking from another person's experience, sometimes men don't see what's right in front of them. My good friend was attracted to a guy. She confronted him and spoke to him plainly about her feelings for him. He also happened to be a good friend of mine and was so taken aback by her declaration he didn't know what to do. He clearly liked her and wouldn't mind being in a relationship. He just didn't dare approach her and didn't think she would be interested in him. I'm like "Dude! She just told you how she felt. Why are you confused about how to respond to her?" The end of their story is they've been married for about 40 years. I don't know how your story will end. There is such a thing as unrequited love, i.e. love that will never be returned. But nobody is a mind reader. So if you want to know you'll probably have to go the direct route and just tell the guy.
