OP, for real...I had my last serious relationship from match.com. The site is hit or miss (like any dating website). I wouldn't spend money on match. it's free to view profiles, but if anyone contacts you, or you want to contact someone, it'll cost you. Sometimes I think they used bots to send emails to get people to pay.
Never tried OKC, but my coworker met her bf there and they've been dating for about 6 months now and are happy. I think the site is free, too.
Tinder has expanded outside a "hook up" app. Like someone mentioned, you can meet someone looking for a serious relationship on there. However, you're limited to a number of swipes per day unless you pay 10 bucks a month for unlimited swipes. I have met some good people on there and had good dates.
Hinge is another app you can try. Supposed to be for the "looking for something serious" crowd. Similar to the tinder "match" set up. Have had good dates from here, too.
Coffee meets bagel gives you one potential match per day.
Bumble is similar to tinder (started by the same person), but when you match with someone, only the woman can initiate conversation. So you have to make the first move or the match expires in 24 hrs. The guy can give you a 24 hr "extension" to show he's interested, but you still gotta initiate the conversation.
HTH. Slow morning.
