I just want to throw this in here-
I am 31. Not married (legally) and we have a 3 year old child and have been together 7 years.
We dont believe in this whole religious concept of marriage being a necessity for a couple to go through.
Legally though.. is another story.
In the event that he ever died, I would NOT get a single drop of his insurance coverage, his left over income, and I might be locked out of our bank account completely.
Our daughter MIGHT, but a DNA test would have to prove that she is truly is child. And then, what ever she does recieve, we could not live off of as it would be put away until she was 18, or what ever legal age is seen necessary by the court.
For those legal reasons alone, marriage is next to a necessity.
So, dont feel pressured to do it as a label or brand to society.
Your relationship is not made better for it and it doesnt effect " your soul"
Just make sure that you are aware of the effects if one of you ever dies and you are living a life where you heavily depend on the others income.
