This lady wants to know why men prefer slutty Instagram celebs to good Christian girls?

I am 26 years old, a lawyer, born in the UK, a great cook, I'm a church girl also in the choir, my skin is my original skin tone, team braids or natural hair, no Brazilian hair or extra eye lashes, I don't drink/smoke weed. I know my worth and I'm fun to be with but I'm still single. It's very annoying because I have all the qualities that a good wife should possess, but I don't meet or attract serious minded guys. All the guys I meet are full of deceit, very childish, they lie they are single, always at the club every Friday, some still sag their pants in 2015?, some borrow money & cars just to impress, sharing apartments with friends. The painful part is that few good guys who are single and I like are always after the so called "IG big girls", with bleached skin, Brazilian hair to their knees, red lips all day, posting ass pictures on their pages and tweeting, always in a beach house on week days, post private jet pictures but they don't have private jet money. My question and curiosity is why would a man skip a good girl like me and go for these girls who are clearly not willing to settle down or don't believe or understand what love is? Do I need to throw away my values and lifestyle? Or do I start posting ass pics on IG for men to take me seriously.

Secondly, married men also come at me so hard and desperately they say their wives bore them and they only married because of family pressure, their wives ain't good in bed. All these things just make me wonder if marriage/relationships are for me and if they are worth giving a shot. 
My friends who are married discourage me from getting married, they say it's a living hell so many stories of how their husbands don't eat their food, they find used condoms in his car, always having emergency meetings at night, and how the sex life is horrible or nothing. How will I love myself when being myself isn't getting me far? Relationship wise I mean. 
I am curious to know if it's only me going through this.
