Is it right to tell him my age?

There is this guy I have been talking to for 7 months. He’s 23. I am 17. He’s 7 years older than me. I know what you are thinking, that it sounds completely ridiculous. I will confess to you that I am not in the slightest considering going out with him now. Although, he told me last night he wants to know my age so he can “take into consideration what may be the future for ‘us’ “ meaning that he is most likely thinking of what it would be like to date me. We are most definitely on the same maturity level, even more so, I believe myself more mature than him; for he speaks like a five year old. It’s like talking to someone who is convinced 2+2=6, when we all know, inevitably, two plus two is four. Regardless, I enjoy talking to him and have come to really like his personality. I am terrified that if he knows my age he will shut down any thought of the future. Because come I am 19 or 20, I would consider going out for coffee, or something of the like. He has asked me to go out for coffee or toast, or just to the mall on so many occasions. I have said no about my age from the start, just because I didn’t think I would be talking to him this long, but alas look, it’s been 7 months and come August we will have known eachother for a year. All through internet, texting, and phones. We have talked on the phone for hours on end, last night it was 3hrs.

I don’t know what to do? Do I tell him even though he’s told me he will not judge me? In the pattern in which he talks, I have come to the conclusion that if I tell him he will withdraw. I can just sense it.

I think I’m starting to possibly want to get to know him more, what do I do? What should I do, and what do you think his reaction will be?

Please help me…
