It's good that you want to have a child as a married woman with a man. Focus on that goal first.
Don't waste your time dating a man that doesn't want you. I would give him a time frame of 6 months before you pop the question. It's not the most romantic way, but it will let you know immediately if your man is about love or sex. Men that are about sex will never truly acknowledge you like they should because they are already getting everything.
Next, I am concerned about your health.
I am not a doctor, and I don't want to give bad advice. However, now is the time to reevaluate how you are living your life. Do you have to get a hysterectomy for a cyst? From my understanding, cysts are tumors that aren't cancerous. I would beg your physician for other strategies on how to deal with that problem. Cysts should be drainable... you shouldn't have to immediately turn to surgery unless there is a mass collection of them.
Secondly, I'm not sure it is healthy you having a baby with the problem you talked about. There are options with surrogacy, where your egg would be put into another woman... one of the centers around here that does that covers the procedure with insurance.
But if you decide to take the risk, please eat healthy and eat a lot. Don't be starving yourself. Now would be the time to eat anything that is green, leafy and fruit or vegetable. You should also open your mind up to foreign fruits, like plantains or jackfruit. Supplements are also a good choice, being that they infuse you with a wealth of nutrients that are hard to get with our Western diet.
I would not let a doctor take my uterus unless I had an official diagnosis of cancer.
My father had a tumor the size of a grapefruit in his stomach and he had it for years. It wasn't until he fainted at work that we discovered he was toxic. The doctors did remove it, because at that point it HAD become cancerous. But if he had the cyst drained and/or was healthier to begin with his body could fight the problem on its own.
But anyway, stay strong and I hope my advice helps. Keep your faith up too... pray every day that God gives you a fitting solution to your dilemma.
