I'm subconsciously rushing to marry, need some advice _/\_

I've observed that I'm unknowingly rushing the process and becoming impatient. How do I stop this?

I'm 26F, and the AM search started 1.5+ months back. My experience with the first prospect was really negative, he (and his entire family) seemed like scam (love-bombers). Even then, I was bent on making it work (I am just not used to failing/ losing), agreeing to conditions such as cooking after work, staying in joint family etc. - thankfully, my parents pulled me out of it, i was too blind to red flags. I was infatuated with him because of talking daily, and had become adamant on marrying him. It's over now.

I'm earning well (it's in the range 70L+) and look above average (not the best, but good enough, and I'm slim/tall). One of the major flaws is that I'm introverted/ shy so I usually cant speak much to a guy or his parents, I become really nervous / panicky. I'm nerdy, and most of my day involves doing my work which is R&D (research), looking up new opportunities, exercising, watching tv, etc. i'm not very social, but i'm confident.

After the first guy, I have felt a sudden impatience to marry. Idk why. I need someone to ground me, please.

I'm 26f, :

1. What is the maximum age among women to do arranged marriage with early thirties guys (say man of ages 32-33). Do let me know.

2. How much time does it usually take for a woman's marriage to get fixed in AM? We have started since January.
