So it sounds like somebody is trying to match you up with someone but you're still getting over someone else and can't bring yourself to think about this new person. <br />
Well I think you need to tell your match maker friend 'no' because it would be sad and unfair to lead on someone who is probably wonderful and doesn't deserve to be hurt. I think you need to tell them and stay true to how you feel.
If they push you together and it works then they will forever remind you that they were the ones to get you two together...who knows maybe they think they are doing you a favour.
Tey want to help others find happiness.
