In this day and age where there is this thing called the Women's Charter, men would be wise to remain single.
Yes you may have a woman that for all intents and purposes, serves as a wife but never put her legally as one. Have a home together. Have kids together. Fuck each other just like man and wife, but never give her the legal position as wife.
You see, women change when they attain that status because they know the obligations they have over you, legally, financially and emotionally.
You fight her, divorce and she takes your property and you pay for the kids.
Catch you with another woman, divorce and she takes your property and you pay for the kids.
You refuse to take care of her parents, divorce and she takes your property and you pay for the kids.
You refuse to let her go out with her male friends, divorce and she takes your property and you pay for the kids.
No holidays? Divorce and she takes your property and you pay for the kids.
No car? Divorce and she takes your property and you pay for the kids.
No condo? Divorce and she takes your property and you pay for the kids.
No maid? Divorce and she takes your property and you pay for the kids.
You lose your job? Divorce and she takes your property and you pay for the kids.
Can she cook? Clean? Wash? Housekeep? Does she get prettier as she grows older? Definitely not!
Can you demand sex anytime? No. So you're starved and when she catches you eating outside, you're done.
For sure when she hits 50 or menopause, you won't be getting any action from thereon.
It's a losing proposition. You have nothing to gain in marriage as a man.
