After unsatisfactory response on Yahoo Im putting here:
Im live in India , Im telling this in first line because below question may need to know the culture in India and barriers of relationships.
It has been several years I like our neighbor aunt precisely 10 years I like her. She is around 40 to 45 years n Im 32 years. I still find her sexy and hot but my intention is not to have sex with her at all.

She talked with me free share her family problems as well, I too share my issues with her since these so many years. Its not the case that we find solutions but we feel good (at least I) when I share I think she too. We talked around 1 to 2 hrs on various topics.. kind of general chit chat often weekly.

Her husband is died last year it has been more than a year she stay alone because her son always fight with her. But both stay in a same home.

She already shared that Im feeling a alone.

Im really confused and think sometime to say to her but sometime think I passed 10 years I can pass remaining as well.

So my question should I express that I like her since several years on not.. because I don’t have any bad intentions but don’t know how she will react.

Say what to her ?

You already said, you did not want sex with her, so there is no need to express any romantic feelings (not that you said you had them)

You can express that you plan on staying alone at this point, which is your choice.

Please clarify what it is, you wish to tell her, more exactly?

Unless you want to date her, there is nothing to express and you just keep being friends. If you don't know what your intentions are you keep your mouth shut until you do, because things will change after that.

Your friendship has lasted 10 years, and now it has changed because she is now a widow, no longer a wife.

While she may not have entertained the idea of having an affair, or divorce while he was alive, she is now single, and able to pursue a new relationship.

Why shouldn't it be with you?

I don't think the friendship would have lasted 10 years had you not been compatible. It is also nice that you are lucky enough to have had a friend all those years, and have come to know her very well, and her you, without the complication of a sexual relationship.

Perhaps she is waiting, as you are, before perhaps developing the friendship into more?

You do not make your intentions clear; it is hard to tell what you want out of a relationship with her.

When you figure that out, then it is time for you act or not act, on your decision.

In my opinion, age has nothing to do with anything.
