Why date a less attractive girl?

Because being attractive isn't everything. I can't see myself dating an attractive guy with a bad personality. You can be attractive and rude. Attractive and boring. Attractive and unintelligent. Attractive and broke. Looks just don't cut it only for me.

That's a very good point! Looks certainly aren't everything, but what if she's beautiful, with a beautiful body, smart, funny, lovely and intelligent? I'm just confused why you'd pass that up?

I've been wondering for a while, why is it that guys (and girls) don't pick the most attractive girl to date? I know, and I've been told a few times, I'm not a particularly interesting or nice person to look at and I don't feel like I have a hugely attractive personality either. I'm probably a 5 at best, with makeup and spending hours trying to look okay.
But my boyfriend was interested in this girl a year or so ago, who he thinks was also interested in him, and he told me she was probably an 8, though neither of us like to rate people.
He's never had a girlfriend before me, despite liking this girl for months on end, as he said it just didn't feel right with her. I suspect he was scared of rejection though, since I had to make most moves to get us together.
So I've been wondering, though I daren't bring it up to him because he knows I'm insecure already and I don't want to ruin this, why is it he didn't go with an 8 (easily one of the most attractive girls he's probably met) but chose me, who is obviously not the prettiest girl and has some self-confidence issues herself? This girl is his type as well, skinny and beautiful but with big "assets" and I'm a much larger girl with a plain face.
-I know I need to work on my insecurity but I've hated myself since I was young and I'm not sure how to stop disliking how I look, but the question here isn't about my issues-

Maybe because you're genuinely interesting to him, looks aren't everything, she could be an 8 but she also could be boring asf

That's a very good point! Looks certainly aren't everything, but what if she's beautiful, with a beautiful body, smart, funny, lovely and intelligent? I'm just confused why you'd pass that up?

Sorry to sound harsh but it sounds like he 'settled' He was too insecure/not confident enough to make a move on the more attractive girl. It sounds like you have very low self-esteem so you need to work on it- it'll be hard and time consuming but you'll definitely be able to do it! And you mentioned that you're a 'large girl' with a 'plain face' - well you can change these things (the latter only to an extent) by losing weight (will also make your face look better) and wearing nice makeup.

People probs do it so they can have something stable and there is like no risk of them cheating on you. If they wanted to they could cheat Behind the persons back. These people sometimes have mental health issues and depression etc anyway which makes their self esteem proper low so there is little chance of them letting go of you so to speak, they will be very clingy and probably bow to your every demand as they don't want to be single. It's an irrational fear for these people

He's not clingy in the slightest and has quite high self esteem in how he looks, though less so in his ability to talk to people, so I feel like that isn't it.

I only go for the sexy girls yah
