What needs to be done before marriage decision is taken..

I don't believe in horoscopes, so that wouldn't be a factor at all for me. And I don't think you're blood group has to match for two people to be married. So, after the basic criteria of suitability and love and a reasonable idea that you could make a life together and are ready for that step, I don't think there's anything else that needs to be taken into consideration. For me, matching blood groups are irrelevant. If I got married, I wouldn't care if my husband had the complete opposite blood group to mine. And, I'd care about horoscopes even less than that. Like not at all.

the first u ave to do is forget about marriage is a bad idea
