"I saw someone on CatholicMatch I really wanted to talk with but I simply refused to subscribe in order to try and meet them.
"I go a message from a [guy] / [women] and I wanted to respond to them but I simply refused to subscribe."
The harsh reality for people (including myself when I was single) is that if someone doesn't respond to you they are either not interested or simply pre-occumpied with other things in their life or a combination of the two. While that can be tough to take it can often be liberating because you can quickly move on to someone who is interested.
One of my good friends is currently going through the same thing. It's simply not in her budget to join CatholicMatch (especially if she'll have to pay for dates in addition to the membership). Therefore, she just stays a browsing member and cannot message anyone in response.
