In my opinion, he is not being unreasonable because relationships break up, and you never know what the future might hold. Having said that, I was in your position many years ago when ex-H and I had DD. We were definite that, as a couple, she would be our only, and I can’t tolerate hormonal contraception (and we both hated condoms). He flatly refused the snip and it annoyed me at the time. (Tho I then got the copper-coil, which I am positively evangelical about).
Years later, I see he was right to refuse - he is now with another woman, and I have no idea if they are TTC (none of my business really) but I reckon he must be glad to have retained that option. Similarly my boyfriend and I are considering the possibility of TTC in the future if things continue to work out for us - I am certainly glad that I never had a voluntary operation that would render this less likely/impossible.....
So HE refused to be sterilised, and YOU had to deal with it to make sure you wouldn't get pregnant? And you are HAPPY with this, because he could go on to having babies with other women?! WOW!
He had YOU well-trained didn't he?

It's amazing how women's pain is utterly normalised.
All these people coming onto say ooh, risk of pain, 10% chance (from vasectomy), whereas female tubal ligation is a only day procedure, it's so easy... where are the stats of side effects from the pill, from IUD, from pregnancy, from heavy periods.
Honestly the bible said that women must labour AND SUFFER, and people really took that to heart. It's just expected, even from the men who are meant to care for us, even too from women!
Exactly this. It's fucking disgusting. 
I can't believe how brainwashed some of the posters are on this thread. Brainwashed into accepting it's a woman's 'lot' to do the suffering. 
Fuck THAT for a game of bastard soldiers!
