I tried Eharmony for 6 months. Out of that I met one person. I think overall Eharmony matches people VERY badly on what I consider "deal breaker" issues. I typically got people at the opposite ends of religion and the kid issue. It got to the point that I would just scroll down to see the most important things in his life, 10 of 10 times, if he has kids..his kids will be in that section. ACK! When they start out.. "my kids have taught me... ", I just had to delete them.
I finally found a place to filter out some of that..but then I got no matches at all, for a long long time. It apprears that Eharmony does not cater to the CF.
About one month before my ad was ready to expire I got a match, finally. I read it ..and reread it many times. I couldn't find any refrence to kids, so I repsonded. Not only did he not have kids, he's had the big V. He also enjoys many of the same things I do to the point that we have a few acquantances in common. The only reason he never came up on any of the other dating sites was because he lives 50 miles from me. (beyond the distance I would travel)
We have been dating for 4 months now, and I see it going on for a long long time. So, although I would not really recommend Eharmony, I feel I got very lucky. So, maybe you want to stick it out a while longer.
