Generally, people have a short list of prospects they are getting to know sometimes simultaneously. I never quite did this though I think it is wise so as to insulate yourself from over investment, the dreaded issue of oneitis and to help you stay rational. I don't think this is entirely nefarious.
Also, just because you like someone does not mean they like you to the same degree or vice versa. Or even like you enough for a real commitment (marriage). So, that can't be a number one no matter how good they look on paper. It's best to go for someone who is more attentive and honest. Provided this person has something tangible to bring to the table in the interim. Some people will speak about castles in the sky that have yet to materialize which isn't substantive or enough. It's too ethereal and not bound in the present reality.
Some people especially when they are infatuated by you are more keen on getting you to fit into their vision of the future they have in store yet never inquire about where you see yourself too. I consider that to be selfish and almost like you are seen as an extension. Generally, if someone never asks me about my short, medium and long-term goals I don't think I can consider them a real prospect. It's all sheeko la'an. Imagine someone who wants you to relocate yet doesn't realize the cost this will have on you considering you have your roots in a particular area and networks established there also. Alas, a lot of nimaan expect spousal relocation (for women only). The only way that would ever happen is if they are ballin' and I see objective proof that (via property taxes, assets/holding and financial statements). Otherwise, I'd be skeptical.
