It will work out how it's supposed to. Not to say you will have kids or you won't, but I have three close girlfriends who each met their husbands after 36 and went on to have children with them.
I am recently divorced and in some ways I regret choosing my ex-, but many positives have come out of the situation. I have two kids, ages 3 and 7, that I think are wonderful people. I am so glad I have them. I love my ex-husband's family, in some ways they are more like my family than my own. I also had about ten great years with my husband before the past few when everything went to s***. Many people don't get ten great years of a marriage.
So, sometimes I wish I didn't have to work so hard to be the sole provider for these kids. Sometimes I wish I lived back on the west coast where I grew up rather than the midwest. Sometimes I get scared I will never find love again. But, I just have to focus on the positive things. It's hard to do.
