In my early 30's I broke up with (so far) the love of my life as he changed his mind regarding marriage and kids and it was THE most important thing in my life.
I wanted to be free to meet someone who would be a good husband and father.
Unfortunately, I'm now nearly 40 and single and childless.
Over the years since him, there have been a couple of men who would have married me and had children with me quite quickly but I didn't love them and, being honest they wouldn't have been much fun as fathers, they struggled to let go and were quite miserly. I believe in marriage for life and with these two men it felt like a death sentence.
So I could have had love but no marriage/kids.
Or marriage/kids but no love.
The pandemic stole some time from me in terms of dating which I can't get back.
And I wanted SO much to be a mother that not having kids made me suicidal around age 35.
However, I don't have any serious regrets. The love of my life would have been a terrible father. I would have been an unhappy wife and mother had I married either of the other two men, and I doubt our kids would have had happy childhoods. The sperm donor route is something that I cannot personally reconcile with my own value system and I'd find it very hard to live with myself intentionally creating a fatherless child for my own selfish reasons.
So life worked out this way, and as painful as it has been slowly seeing motherhood ebbing away from me, I've ultimately accepted it and don't regret my choices.
It was always going to be love + marriage + kids, or nothing. I've stayed free to meet the right man to have all that with. The wrong man is not worth losing that freedom for.
