i. Are you spiritually compatible? Is he Catholic and you're Pentecostal? Are you of the same religion? Are you willing to change for his sake?
ii. Do you know his long term goals? what he wishes to achieve in the future, where he sees himself in the next 3, 5,10 years? Because a man without a future or plans to have one is not yet a man, in my opinion.
iii. Can you imagine yourself living with him? I'm not talking about your roommate you hate back in the university or your housemate that if they get on your last nerve you can change hostels or change houses, I'm talking about sharing a home! You have issues with your space or people touching your stuff, moving things, silly things like leaving the toilet seat up, laying things around have been known to break homes apart. So make sure you're willing to compromise for that special somebody.
v. Is he your friend? You should be able to tell him stuff about you,you shouldn't have to make him ask, just talk to him the way you talk to your bestie Adam or your bff Esther, it shouldn't be such a big deal!
These are just few things to consider,there are a lot more. You should not be doing it just because everybody else is doing it, after all, after the wedding everybody will leave you alone with him. We can't change the mentality of catching our fishes in our final year or during NYSC, 'cause, after all, this is Africa
