I think what you really want is to see if he is willing to meet you and see if there is any hope. You may achieve more by being direct and I agree with PP doing this by speaking to him rather than texting may give you a better idea (and also you won't have texts to pour over going "but what did he meeeeeeaaaaaaaaan?"). Eg. if his answer is "I'm sorry, I've just got engaged/I'm not interested/am currently dating Elle McPherson" it's better he says that to you and is forgotten than you have a text to torture yourself with.
Separately, read this - it's written by a man. I've posted this before and someone said the guy that writes this site is a misogynist - doesn't mean that there isn't a lot of truth in this post though!

I can’t count the number of girls I have decided to stop contacting after dating once or twice, or sleeping with, or even just talking to on the phone, who decide it would be worthwhile to call or text me a week or two later, apparently under the false impression or hope that I had simply forgotten to get back in touch with them - that I merely needed a reminder.
In one case I slept with a girl and even hung out with her a few times before I decided I didn’t want to continue seeing her. So I stopped calling her. Within a few weeks I got a text: “Headed to pacific beach, Wanna join?” I didn’t want to join, so I ignored the text. The next day, I got this: “I’m in your neck of the woods J.” Again, I read and acknowledged it (with a heavy dose of apathy), but did not respond. Then, again, over a month later: “Driving through your neighborhood and thought of you. Hope you are doing well J.” What was this girl hoping to accomplish? Did she really think that this would suddenly rekindle my interest?
Although I acknowledge the remote possibility that girls might just be fishing for sex in these situations, the thought of a girl having to do anything other than agree to male propositions in order to get laid is far more repulsive than the idea of a woman trying to salvage an obviously failed relationship; so I refuse to consider it. It will be the subject of another post. In any case, in this situation and others, I know from the circumstances that the girl wanted more than sex. So back to the original question: did she really think that this would suddenly rekindle my interest? Even if I did have some lingering interest in talking to her, it is hugely indicative of my overriding disinterest in a girl that I would actually forget to contact her for an extended period of time.
Any girl with an ounce of pride would not submit to this kind of treatment by soliciting further interaction. If a man decides to break up with a girl, or that it isn’t worth his time to get back in touch after a date or exchange of numbers, that is his decision. He needs to live with that, however easy or difficult the decision was for him to make. As a woman, you need to make him live with that. Men should be given one chance, and one chance only. Trust me: if we are really interested in you, or are at least physically attracted to you, we will take the opportunity you provide. The act of attempting to reconnect after you’ve been dumped or rejected or ignored only comes across as needy and insecure, two of the least attractive qualities.
