Feyth I have been in this position and it's not a choice anyone should have to make. And there is no right answer there is only life, and making the best decisions for you at the time they present themselves.
GAL, and become emotionally and physically healthy as you can be and hand over the rest to your Higher Power, or to whoever you feel is walking this path with you.
Some practical advice, go and have your fertility tested NOW. Find out what your body is doing and this may provide you with a wider lense with which to view your sitch. For all you know you are running on the fertility hormones and have a bountiful amount of eggs, that of a 25 year old, or you could be at the other end you could be running low and you may need to consider preemptive measures.
Sorry Zues I am disagreeing with you here ( I know your position on no divorce at any cost - and in most instances I would agree).
It is one thing to come to infertility (biological reasons/ or unexplained infertility) as a couple and choose to move through it, over time. But it quite another when one person desires children and the other does not.
If children are an absolute non-negotiable and are a heart and souls desire for you, please don't compromise this.
Not having children is definitely something you can live with. I have a great life and get my needs met through my work with children and the children of my friends.
In saying that there is a piece of my heart that will always yearn for something I can't have. A relationship where one has compromised this kind of hearts desire because one party didn't want it, is posion to a relationship in my opinion. To work through it with a partner takes great commitment, love and intention.
The other thing I potentially would caution you on is the rush to find the father of your child. When the pressure is there to find this person, we can fail to fully take account of the person we are considering. I hate to say this, but I will say it anyway (likely to Zuessy head shaking at me - I think I often provoke this response - Love ya Zues). I always hope that the qualities that make a great husband, will make a great father and vice versa. This is not always the case. Choose wisely Feyth. Sometimes the deseparation to have children can make us blind.
I really wish I had discussed this issue with a counsellor or therapist and came to my hearts desire, prior to completely losing the opportunity. I would have made different choices.
I really do wish you well. This road is a challenging one. But please know life is good regardless.
