Marriage Advice

Met a person on matrimony. Later knew that both families know each other. I have never personally seen or talked to them before. That person is in IT and earns good. I am also into IT and earn more than double their salary.A nice person with values. I am an extrovert. I talk a lot and share a lot about my life.But they were an introvert. They said they were putting efforts to talk more and share more but couldn't fully open up at a pace i expected it's been more than a month. They love to listen to me though. They are more homely. Both our financial backgrounds are similar. But they were bought up in a more restricted homely middle class manner and I am comparatively more modern outgoing have lots of friends and social life..they are okay with adjusting and even mentioned their liking after repeated asks..They don't have a great friends circle or a passion or ambition and more of a go with the flow type. They initiated a silly fight because of over thinking and even apologized later. But I feel we have lot of difference in the lifestyle, friends circle, ambition. I am doubtful about this alliance. Any advice or suggestion would be great.

Hello Gs Help a brother out with your unique research strategy to understand how a startup (early to series B) is doing in terms of financials and operations? Here’s my list of to dos before interviewing with a startup to understand their financial health - LinkedIn - crunchbase - press releases ( always with a pinch of salt) - asking the C suite directly during interviews ( sometimes too late and again with a spoon of salt ) Culture - ambition box - Glassdoor - ex employees - personal network if valid
