Thinking marriage will solve all your problems / putting life on hold - when I find someone it will be different type of thinking
I think marriage can solve a lot of problems. The primary items I can think of are, 1) loneliness, some things in life are better when shared with someone else, 2) having kids/ descendants (if you plan to leave inheritance), 3) a combined income (if both spouses work), can increase quality of life, and 4) possibly most important, having someone nearby when you need some help (moving, in sickness, etc.).
However, this doesn't need to be said but marriage can cause/create new problems too. The primary items I can think of are, 1) not on the same page on important issues (sex, finances, kids, outlook, etc.), 2) shouldering/dealing with the sins of someone else (porn problems, gambling, dishonesty, etc., and 3) control/passive aggressiveness issues (when one spouse feels he/she should have his/her way and should not compromise).
