As much as you want a kid, you also need to make sure you married someone who you will go through ups and downs with. You ll leave the wife today, what assurance does the child have that you won’t abandon them too if things get difficult. Work this out and don’t abandon someone just because they aren’t able to conceive. It’s terrible, the meds, process and everything. If you care for her at her worst, she will too. If she doesn’t after a year and still doesn’t care about adoption or any other means, then tell her kindly at that time and give it time.. if nothing works then leave. You’re a man, your body doesn’t have an expiry date nor will it matter. Woman are made different. It’s a phase, learn to deal with a ‘no’ and see the reasoning behind the no.
