How do I move this relationship forward?

i have a male friend who i have known for over 5 years…he is my financial advisor…during this time, he has asked me to dinner and various other places…there have been times when we could have been intimate, but i wasn’t ready to take the relationship there…i must tell you at this point that i have been dealing with the sudden death of my then 20 year old son (brian died about 5 years ago) and subsequent divorce…

fast forward to sept when he asks me to accompany him to nassau (he travels a lot for business/pleasure) i accept with some trepidation…i wasn’t sure i could be with someone for 4 days without “zoning out”...which is my term for my behavior when things become overwhelming…well, everything was so relaxed and fun…he was relaxed and fun and i began to see him differently and i felt closer to him…we did not make love, but did have some intimate moments…he made some very complimentary remarks…and even said that he would enjoy doing another trip…

we arrive home and i sent him a thank you present…we spoke on the phone…he had a trip planned to egypt and a business trip…but he said he wanted to take me to dinner very soon…(we live 1.5 hrs from each other)...well, i know he will call, but i feel at this point the die is cast and i will have to tell him of my changed feelings…i would like to take this relationship to another level…the only problem is this…if he doesn’t want to, what would happen to the friendship? does it matter? should i just go with my instincts? i know i probably should know the answer, but i am a very emotionally fragile person at this point…i am moving forward as i deal with brian’s death, but i have to say, it is a very slow arduous journey…any comments would be appreciated…thanks
