Odds are you know far more than three women who have had abortions, but the ones who don't have any regrets aren't dwelling on it so it just doesn't come up in conversation. Statistically, most women do not regret the choice they made (and among those that do, there is often the common thread of not feeling like her choice was freely made).
Every person should have the right to make decisions for his or her own body, period, full stop. In a healthy relationship, of course the couple would discuss a major decision like this and seek to reach a mutually agreeable resolution. But when you say a husband should "get a voice" in a woman's decision to have a tubal (or a wife in a man's decision to have a vasectomy), you're saying that marriage makes a person something less than a fully autonomous human being. Not to mention the whole can of worms it opens for those in abusive, toxic or unhealthy relationships.
The same is true of abortion. One of the reasons adoption is an unattractive option for American women is because the father gets a say. And that say often comes without consequences; by stopping the mother from giving the child up for adoption, he's not obligated to take custody. He's just as able as any other man to skip out on even paying support, and if he's abusive or controlling, he's got a "tool" to use for 18+ years to manipulate the mother.
You talk about your friends who have regrets over choosing abortion. I know two women who deeply regret trying to choose life, because in both cases the "father" said he would support the choice to give the baby up for adoption... until the pregnancy was too far along for abortion to be a choice (because contrary to popular believe, elective late-term abortion is not a thing). Then one skipped out completely, and the other became an all around horror story - he was emotionally abusive right along but became physically abusive after the baby was born, and when she finally got herself together enough to leave, he became the ex from hell, getting her fired and evicted by showing up and making scenes, taking her to court to keep her from moving far enough away that she wouldn't feel like he was just around every corner, fighting for 50/50 custody on paper to reduce child support but not showing up reliably enough for her to count on him as childcare on his days, picking fights with and harassing men she tried to date, using CPS as a weapon, etc. She loves her child very much and has done everything she can to make a good life for her despite all of the hardships, but among close friends, she wonders often what might have been had she chosen differently. The other woman, on the other hand, well... she's not much of a mom. Her son has been removed from her care on multiple occasions because she basically decided to live her life as though she wasn't a mother, partying on the weekends and having assorted men in and out of her life, and she's never taken real care of the child. She's made no secret of wishing she wasn't a mom, and unfortunately, the courts keep pushing reunification (a rant for a whole 'nother thread) so he has no chance of getting off that roller coaster.
