I knew my bf from okcupid (a dating app) when I was 29 (he was 31) in 2013. We're ROMing end of this year, and holding our banquet next year.
I've to say I didn't choose to stay single, have had past crushes and got rejected. I guess because I'm not an attractive-looking girl, and my character makes it difficult to attract guys who starts off as friends, because they see me as their bro.
In my early-20s, I was still alright, and thought maybe I'll meet my Mr Right soon.
Then in my mid-20s, I spent a lot of time at work, social circle stuck to existing friends (who see me as their bro) and colleagues (either attached, married, or very old). I did feel very jaded, and was already planning to buy a HDB flat when I'm 35. Lol
And then when I reach late-20s, my friends started to try to matchmake, other single friends invited me to attend speed dating events, which I find is actually quite fun (though tiring because you've to introduce yourself for 10 times at least). When a friend and my sis told me about their friends who used okcupid, I decided to give it a try, and managed to find my bf from there! For records, I started the conversation first haha!
Not all guys are out to look for sex in the app. Based on experiences, it depends on the type of app you use, and sometimes it's just the profile pic you use. I have a friend who meets guys who're looking for sex no matter which app she uses, and we concluded it's because of her profile pix. Lol
So my advice is... if you don't wanna stay single, then don't expect your Mr or Mrs Right to fall from the sky, go out and meet more people, and don't be afraid to strike up a conversation first!
