If I said “oh I know just how you feel” it would not seem true at first. Even though I long considered myself unattractive and unworthy of marriage, two members of the opposite sex thought otherwise and I accepted those offers ( a few years apart), much to my regret. After we said the I do’s we all wished we had not a few years later. I was not acceptable after all, neither were they. We all just put on a helluva show for each other at first. Now I know I am unacceptable for marriage, I am here aren’t I?
As for having kids, about 70% of Canadian parents surveyed would not have reproduced if they had known then what they know now. Likewise.
I know it is normal to want marriage. I read that about 92% of American adults will be married during some part of their life. Just as telling, less than half of American adults are married. The stats on this may have changed a bit but the underlying idea is still about the same.
If you feel like shit for still being single you do, but as a single you are now in the majority. Speaking for the minority, marriage is rarely all that good. In fact if you feel like shit now, an abusive or heart turned cold spouse could make it much worse.
