Yeah I don't think you should ever settle again, it's pointless and neither person will ever be happy in a relationship like that. Meeting people seems to get harder and harder as you get older. Especially if you work with a small group for a long time with not a lot of change and don't have a huge social circle. If I were single I wouldn't even know where to start looking but it's not impossible. I think you just need to go out with friends more, go to parties, go do fun stuff like go bowling or basically anything that makes you get out with people.
