Hi sunshine,
It's nice to hear that there are someone who wishes to know you, we
all come to a point when we are attracted to the opposite sex. But
it appears that no much information is given, and you aren't really
sure whether is he really interested in knowing you better or just
remain as a friend.
I would advise that you think of the whole situation as just normal
friend, in order not to give you false hopes or wild assumptions.
Remain contact with him, and lead your normal life as well. Stay as
friends first, he may just be physically attracted to you or a
crush only. I'm not saying that you ain't worth his attention or
love, afterall you did attract his attention in the first
place.
If you aren't sure, go out with friends or colleagues and invite
him along. Take notice of his response and reaction if you must.
It's always this little thingy, "he/she is trying to know me",
"he/she keen to get close to me" that we tends to develop the same
feeling for that person, esp if you are single at the moment. Take
his intention as a compliment and stay in touch as a friend. Get to
know him better, and let him know you better too. From there, you
will know whether both of you have a chance to take one step
further.
By the way, age shouldn't be a problem. The main reason, though not
directly, why we consider age as a factor is because of the mental
side, whether the person is matured enough, so on and so forth. If
he is sensible, responsible and matured enough, don't let age comes
between you and him. I know of a friend's auntie whose husband is
10 years younger than her. But they are happily married and have 2
lovely kids...and they met in their workplace too!
Just be natural and you will know in time. Cheers
