sometimes sellers aren't really that interested in selling;sometimes they are so unreasonable or so unrealistic that they NEVER get the property sold. i've seen this happen quite a few times.
i agree with the other responses you've had: make an offer, specify exactly how you want it to go, they can take it or leave it. at least if you submit a written offer the agent is obligated to present same to seller. (at least in the state where i've done most of my business). so you'll at least know it's been seen.
also, they just may be cagier than you think. maybe the non-responding is calculated to draw you out, get more out of you. it's always possible that if you stop communicating, they'll come looking for you. sometimes negotiations really do go on for months.
