I read your post in the morning and thought near all day about it. What can I say? I had an unhappy marriage in my life, but I think it was because of that social cliche. All friends got married and I was alone. I thought it is my fault and married the man who was saying that he loves me for 5 years. I thought love is not so important in a family. now I understand that it was wrong. I don't feel lonly. I am a person who is always busy and don't have enough time for everything I would like to do. I asked myself would I want to try again to be married and couldn't answer. I think people are getting borred with marriage, because some of them think that the ring gives them owner's right over another one nd they forget to look after themselves. They don't work anymore for their relationship to be fresh and strong. They start to wear old clothes at home and behave not in the best way, because if he/she is their wife/husband, they won't leave and will tolerate them. If there is big love, you better marry to make your partner understand how much you care, but don't stop working on relationship, because love is a hard work.
Good luck to you and I wish you will meet one day that girl, which will make you to forget this post and ideas written here.
