Have you ever thought why a person who drinks does not stop. He may start with one drink but wants to have more, because he gets so much fond of the situation that he is in and he never wants to come out of that. Even knowing that he is doing a wrong thing or that his drinking can deter his health he cannot look ahead because he gets so much conditioned to the way it is. You are also doing the same thing. Someone who does not want to move forward because you feel this is simply the best. I have two things for you. Eight you just be happy with what you have and stop dreaming about something better or simply close this here and move ahead.
You are grown up and mature to decide what is in your interest.
