My best friend..

He is the best guy friend in the world to me, but he keeps me in the friend zone..why?
He is 38. I am 44. We have known each other going on 4 yrs now. I visit him every Saturday, we play yatzi, uno cards, and dominos.
We talk about his dog, Kia.
We talk about how our future plans will be to see the world..but we never go on a date..we dont eat out together..we just talk.
Theres never been any intimacy, no kissing, no touching..just talking.
I REALLY enjoy his company, but he says im not his type..so i love my best friend..but how come he only calks me to talk? He has been there through thick and thin, ups and downs, rights and wrongs..and all we do is talk. Maybe im just a friend, but i wish i was more....anybody else ever feel this way?
How do you handle it?
Everyday he calls me, i answer the phone with " HELLO HANDSOME " and he responds, " Hiya gorgeous "
We write letters and at the end of every letter he signs, all my love 1434..i asked what it meant he replied, i love u more..so what gives..am i dreaming too big or is it just a brotgerly love type thing?
I wanna know what hes up to..honest Answers and advice are appreciated!
