Need an advice urgent- decision had to be told in 2 days

Hi , I'm 29m working with salary of 85k, my co worker in same office 26f earning same amount of salary,3months before,i came to knew that she belongs to same caste as me and same dosha as me for horoscope matching, after much of hesitation I asked her for alliance, initially she was shocked and refused stating that it won't be good to seek alliance in workplaces. I accepted her decision. But after a week she gave her horoscope and stated that her parents were not seeking alliance seriously now , if I told about this they will mistook that we are loving eachother, she told she will tell her parents about this when they start seeking alliance seriously, meanwhile don't wait for me, if you got other alliance for ahead for marriage as she doesn't knew when her parents will start seeking alliance. I was really confused whether it is positive or negative reply whether to wait for her or not. While last 3 months we acted normally as friend, but i kinda developed crush in on her, now I got another good alliance where they expect me to tell decision within this week, what should I do , Is it wise to reject good alliance for waiting for my crush to tell yes believing in her words (which is not confident inspiring as words of people in relationship itself have low value these days) or should I go ahead with alliance as time is running out for me as I'm nearing 30s but my crush is younger age of 26 can afford to wait for few years while time is running out for me??( When I asked her again that should I wait for you , she again said same reply of don't wait for me , but since I have some crush on her I unable to take decision due to her confusing reply).
