To any of the guys here having frustrations with being rejected, note my advice from observation. Be self reflective and take action. If you are seeking out good women and constantly being rejected you have to look at yourself objectively.
I have read a few responses that obviously show instances of scruples, obsession, anti-social behavior, not having or sharing well-rounded interests and emotional/mental conditions. This is not appealing and not addressing these things is being weak and not being the best you possible. A good woman should be with a man who is brave enough to tackle these things. Also, no healthy relationship can thrive if someone needs treatment. I have had battles with depression, anxiety and childhood trauma that are now being resolved with the help of spiritual direction and therapy. No way was I ready before for a serious relationship no matter how much I wanted it.
Every man I have personally encountered who has consistent dating issues is not being self reflective and is not devising next steps. I’m on CatholicMatch and see this time and again and these men are wondering why they, good Catholic men, cannot find anyone. It is no better than the secular world. Being a good Catholic man is not enough. I get approached by men young and old that are not appealing for a number of issues. The older men have mostly never been married and I can’t help thinking that they never took an objective personal inventory but often just say they are rejected and women aren’t looking for a good Catholic man. There has to be a reason why THEY are still single. I feel these men need Jordan Peterson in their lives. He tells men to work on themselves, become appealing to a broad number of women, pursue and then choose. So simple and it works because it’s basic biology but many want to think they are victims, thus the incel culture.
There are fickle women, especially the younger they are, but any attractive, good Catholic woman who is well rounded, mature, realistic and open to marriage will find a guy who is the same and will give him a chance. It is not any easier for women, despite what some think. I would love a man that I am equally yoked with to pursue me, but instead I get socially awkward or mentally imbalanced men who expect a date just because they are devout. Or there are others that seem to expect to marry the Virgin Mary but that is a whole other issue.
Someone up-thread asked why Catholics are choosing non-Catholics. I will say this, a Catholic man is currently my top priority, but if things continue as they are I will broaden my search to a man of strong Christian faith and if it works out I will know he is who God intended. If I find nobody then I will know it was not meant to be, his will be done.
