ok, so I told him how I felt & got no response but his brother says he really likes me........?

I don't blame you one bit. It is hard to be in your position because despite all your attempts, he doesn't come to the table. There is only so much you can do, and you are doing it. So the situation as it stands is not for a lack of effort...

I think the barometer that I tend to use is to ask myself if this type of (characteristic, quality, habit, etc) is the type I am looking for and how far could a relationship go with this person. Yes, this does sound a bit like High School when a friend of a friend of a friend is asking .... blah blah blah... Almost sounds like you need to corner him face to face to get a straight answer.

I guess he feels more comfortable in a texting kind of world.

It sounds crazy that he prefers that over a real conversation and for him not to respond to your letter may indicate he is not emotionally mature.

And if you're wanting to take this relationship to the next level, then it's time you set the bar level and if he doesn't meet those standards, then find someone that can.

You need to call him on the phone so that you have no doubt that he knows what is up. Lay it all out for him and what is the worst thing he can say? He isnt interested? Then at least you can go forward and not backward.

if he needs an interpreter you need to find a real man
