@navySea3717 I know not everyone believes in God, but I do... so when I mention Him, I'm only speaking regarding my beliefs on the topic you mentioned.
I believe it's not God's will for everyone to marry. With that said, no, marriage is not "necessary" in life as not everyone will find a husband/wife for them.
But I believe human touch and companionship is very important, and having a partner can be a good thing. Just because someone is with someone does not mean they have to marry.
And even if you love someone that does not mean you have to marry to confess your love.
But I believe, marriage is a beautiful thing when it is between 2 that love each other unconditionally. Marriage means that I have a partner for life, to help bring out the best in me, someone to be there for me through the good and bad, someone to help me grow, and just someone I know I can count on while I go through this thing called life. And vice versa.
I have no regrets of marrying and have been almost 10 years and still have a lifetime to go. Because of it being God's will, I have 2 children that are products of that love. I know it was no one but God that brought my husband and I together and it is Him keeping us, as well. This is fact in my book.
Children are a lot of work and they require so much. Being a parent is truly a blessing, but at the same time, it is hard work. I could not imagine being a single mother or wanting that. Raising children is a struggle enough with 2 parents, so I can't imagine how it would be falling on only 1. I love that you mentioned adopting kids though because there really are many kids out here who need that love and someone to call theirs. However, sadly, the reality is not everyone meets the qualifications to adopt a child no matter how much love they have to go. That's just life.
In whatever anyone does with their life and in it, I wish them complete happiness!
