Marriage is a huge decision which needs to be thought well. Of course our parents decide best for us. But as it is our life, we have all the right to know our would be partner well before marrying. 

1.Knowing your partner's parents is important. 

If you are marrying a guy who stays with his parents it is very important to know what are his parents expectations.Most guy say that they value your independence and choices and you are free to do whatever you like but if my mom says anything please don't say no. This sounds wonderful that he'll have your back, but your missing the thing about parents. You must respect your in-laws but do not get into such relationships if your life and their expectations don't match. 

2.How you both handle finances. 

There are people who believe in saving money and there are people who believe in spending money  Of course there need to be a balance but you need to know well before marriage how your partner manages his finances. Or is he the only person earning in the family, or are they into any loan, because mostly these things come as shocks to many of the womens. And then we don't know what to do. 

3.Discuss about Family planning. 

Family planning disagreements comes with so much pressure especially for the women. So it's very important to discuss this about what are his plans regarding kids. When does he want to have kids? How many kids does he thinks of bringing up in this world. What would he do if you couldn't give him kids due to some medical reason. These questions need to be worked out well before marriage and do not marry someone who's family planning plans don't match with yours. 

4.What he thinks about daily chores. 

I won't suggest to go deep down into this topic but it's good to have a shallow conversation about this topic. Like you can just share your thoughts whether you like cooking or grocery shopping and that you just prefer keeping a maid for help, and all that, especially if you both are working. If you are a housewife you can just find out with small talks about how he thinks about men doing house chores, does he think helping women in chores a good thing. Just ask him so you have a rough idea what's the chores scenario gonna be like in your future. 

5.Each other's past. 

Honestly your partner's past should not matter. Who they kissed, how they kissed, whom they dated and their names. Its all in the past, it's sometimes ok to discuss a bit to make sure that the past doesn't matters to him and to show him your thoughts regarding the same. Don't get too deep into it. Like you saw thie girl in the college and you fell in love with her and she is the most beautiful girl and all that. These thing's can lead to lack of trust in your relationship. If you are still friends with any of your ex, make sure your partner knows about it. If your not comfortable sharing this, either break that friendship or walk off from your date. 

I hope this was helpful. I will soon come up with a part 2 of it. Let me know what you think about my suggestions in the comment section..
