If you know what answers you want, why are you not applying them to your questions? Or, another way of putting that, how has what you have been doing so far worked? If what you are doing/not doing has not worked, you have to try something you are not familiar with.

If you are lonely, you have to go out and socialize and make some friends; there's no easy or automatic way to do that or any way to get around it; other people are not going to come beat down your door to get to you, especially just based on an online self-evaluation of, "I'm a nice guy, come check me out."

If people read your post and offer suggestions and you "reject" them, how can that work? You are not trying to get to know and be interested in anyone else and yet you want anyone else to try and get to know and be interested in you. Relationships do not work like that, they cannot work like that.
