I know I'm preaching to the choir here, but I never understood why pretty girls degrade themselves by dating/marrying/reproducing with guys who have about as much sex appeal as a wet gym sock. Unless the guy is like REALLY good in bed, and what he lacks in appearance, he actively tries to make up for by successfully making you climax via foreplay and oral every time ya'll do the nasty. At least in that case you're getting SOMETHING out of the looks mismatch.
But if hes not ... Do you think you're being some kind of a good person by "giving him a chance"? You're not. No one who sees you together thinks you're some kind of Mother Theresa for settling. A lack of self-respect is not typically something most people consider worthy of admiration.
You're just screwing up humanity's course for evolution by passing on your boyfriend's ugly genes, and if you have a male child, your son is gonna grow up to be an incel who hates you for not choosing a better sperm donor, and saddling him with his father's appearance. If you have an ugly daughter, best believe all of society will treat her like shit for not looking like an instagram model, and in a world where womens' societal worth is heavily contingent on their appearance, she'll grow up painfully aware of how much she lacks in the looks department and have chronically low self esteem that makes her an easy target for LVM to abuse and exploit. Either way, there's nothing morally virtuous about bringing an ugly child into a world that hates ugly people. I'm sorry, but that's the truth.
You're not doing your boyfriend any favors either, because in the words of Billie Eilish, "you give an ugly guy a chance. He thinks he rules the world. And its like... you're still ugly though!"
Or maybe you're thinking that your inbred methhead-looking beau will be more likely to value/cherish you because he knows you could easily score someone more attractive, and it's a testament to your love that you gave up that opportunity for his sake. A sweet sentiment, but ultimately one that has little basis in reality. As a general rule of thumb, men don't like feeling like charity cases. Even if you manage to overlook the fact that you're settling for your boyfriend, his ego will NOT permit him to do the same. Hes not going to feel lucky for having you. Hes going to feel pitied. And he is not only more likely to resent your pity than appreciate it, but it will motivate him to punish/ humiliate you. Either by cheating or by attempting to chip away at your self-esteem via negging in an attempt to bring you down to his level.
Or he'll just take it one step further by projecting all of his self-hatred onto you and become straight up abusive. If he doesn't respect himself enough to put any effort into working on his appearance, he's not going to respect you for putting up with him in spite of it. In fact, he'll probably justify his cruelty on the grounds that you deserve it for willingly wasting your time on him when you could easily do better. After all, its not like you didn't know what you were signing up for when you settled, right?
Honestly, this post is stupid, IMO. So you're saying that only hot women are worth of good self-esteem? That's pretty anti-feminist and illogical, as if we'd only procreate with attractive guys, we'd have to weed-out unattractive women (since they could give birth to ugly children). Also, genetics don't work that way. Two attractive partners can have an ugly kid. This reads as a really mean post, written by a privileged person. I guess? Also, if we follow your logic, we must weed-out low-IQ people, since high-IQ people contribute more to societal advances. Same could be said about short people, mentally-ill people, etc. Actually, I also find odd when an attractive woman goes for an ugly man, but have you asked them about how they feel? IDK, maybe they genuinely don't feel they're settling? To be honest, I'm fairly unattractive, but my mother is attractive and my dad's ugly. My mother didn't settle and she was attracted to my dad. What you want won't ever happen unless we force society to behave that way, and women aren't a hive mind. I hate how society bully people for things they cannot change. That's the same as punishing a kid for having autism. Just plain vile.
PD: sorry if I sound rant-ish, but this topic really makes me feel like crap.
