WHAT???? Having too many messages to respond to on here is totally a guy problem and why I say it is easier for Catholic guys than us women. The pool of women is much larger to choose from. I do hope that there is a not interested button in place soon. But I also think that a simply note saying "best of luck to you" would convey a similiar thought and also fulfill the charitable aspect of it. Remember men; charity in ALL things. What would St. Joseph do?
I believe it depends on the person's personality. Sometimes, I'm clueless of what the hidden message might be behind her reply. In real life setting, it's like me walking away if I'm not feeling what I'm about to say is good for the other person. I'm not trying to be rude to her and some women do it too when they're not interested. From my experience, most women usually don't care much about giving a "nice rejection" reply. Judging from my history of messages, I've sent more emotigrams than the replies I've received. Also, sometimes those emotigrams have small messages. However, I use the options available for me to contact her and get her attention. By nature I'm considered introvert according to personality tests I've done and from what people have said about me. I actually don't know what St. Joseph would do in this situation other than what you've mentioned regarding charity....
Actually the pool of women for me to find on this website to be very honest with myself is pretty small & to even get a good start on messaging each other. I for one don't live in USA and my age group bracket of women to message in my county is small. I've tried long distance relationship internationally once in the past & it was short lived. So, that leaves me to just casual conversations with gals from USA because it would take both parties to take it seriously. I don't mind LDR within the province I live in or from the other Canadian provinces. Since, I'm a Canadian citizen travelling within Canada therefore I don't have to deal too much with rules applying to international travels.
P.S. I still have to figure out how I can find a way to just search only for Canadian singles on this website. Your searches goes by distance, therefore it make sense that my searches will populate mostly from USA.
