I do have some pointers for online dating. I'm not saying it will work for everyone, it may work for only a few, but at least you're not being fake about it. Remember, if you think you have a better idea, go for it, because I may be wrong, and I was just very fortunate. Ultimately, it's God doing the matching, but He does use people to do His work.
1. Be as HONEST as you legally can in your dating profile. What I mean is, don't say, "I want to marry so I can have sex without sinning." While that may be the honest truth, dating sites usually forbid that kind of talk. What I do mean is say something like, "I'm a Christian who seeks a wife who also seeks a husband." Plain and simple. Don't try to sugarcoat anything. List some bad features about yourself even. It's like Honest Trailers on YouTube.
2. Make your match settings to include ONLY the ABSOLUTE MINIMUM requirements you must have in a mate. Make sure within yourself that everything else is OK with you. Plus, be honest with yourself about it.
3. Whatever matches you do get, quickly skim over them, and message nearly EVERY SINGLE ONE. What message should you write? Well, say "Hi, how are you? I like your profile" (Do remember a thing they said in their profile, and ask a question about it.) This is why I highly recommend eHarmony, because they guide you through the entire communication process before you go into free communication. If you're an eHarmony user, on your first match, ask them five questions that are somewhat serious. Don't start with the icebreakers. (Well, maybe one.) Then, stick with those questions in your match blitz.
4. Assuming you get messages back, promptly reply to them. Stick with the one who you feel is most serious about a relationship and marriage, and that usually happens when they themselves put up some money to write you, as in my case.
I know people don't really like eHarmony because they're so expensive. Well guess what? So is marriage. This is why eHarmony is full of people who are serious about marriage, especially those who make an investment in their premium services.
I know, because I've done that, and am starting a relationship with someone.
Like I said, that's just my experiences with online dating. Yours could be totally different. But the main thing I HIGHLY RECOMMEND to everyone, is BE AS ABSURDLY HONEST WITH THE POTENTIAL DEALBREAKERS AS YOU CAN.
