See. That's the thing. I may not be attracted to men who are say, 750 lbs. But, I will give pretty much anyone a chance within reason. If a guy was 300 lbs and I wasn't really attracted to him, but he seemed like a nice guy, I would give it a chance, on the possibility I could become attracted to him inside and out, as I get to know him.
I'm not morbidly obese. So, I feel like I am within the "reasonable" category, but that's just me.
I am very curious, and this is just me thinking out loud here, it would be interesting for someone with actual online dating experience to weigh in on this. The long-distance throws an extra wrench into it.
I mean, if I met a guy online, he lived 10 minutes away, I could go meet him for coffee or tea sometime one afternoon just to see how things go, and it would really be no skin off my nose. If we get along great, if not fine.
When it is an extra long distance thing...which again, I know it's rare, but I know it happens and works sometimes too. Long distance, it is an investment. An investment of your time. An investment in funds, for hotels or gas money or airfare. For me, it is just not something I could or would do just on a tepid interest, just to see how things go. I would have to be really interested in the guy, really feel the connection, be a little giddy, in order for it to be worth it to make such a big commitment.
Which, it is a double-edged sword. Like you said, it is kind of setting yourself up for failure, to get your heart broken. Putting the cart before the horse. Ideally yes, you should not be SO interested, and not get hopes up, and just let it happen. But, when you are investing that kind of money and time, you should be pretty sure you are on the same page as far as interest is concerned.
