- Doesn’t know how to negotiate a conflict without resorting to emotional abuse or blackmail.
- Uses bullying tactics to get his or her way
- Has a healthy sense of give and take: neither tries to always be the one doing for others nor expects everyone else’s plans to revolve around him or her.
- Self-medicates difficulties with alcohol, drugs, shopping, or other behaviors that develop into addictions or “can’t have fun” without this kind of thing…as in “Oh, man, I need a drink.”
- Cannot reasonably be expected to be an asset instead of an obstacle or “neutral force” in practicing your faith and raising your children Catholic. That normally means Catholic, but there are a lot of people out there who want their children raised in a one-faith home more than they want to continue in whatever it is they were raised with. (I know of one such man who did such a good job supporting his family of Catholics that he was asked if he wanted to run for parish council. The family was very observant, volunteered a lot, and no one had ever noticed that he did not go to Holy Communion.) A person who is “neutral” about your faith will probably grow to resent your religious duties eventually, however.
- Has friends he intends to keep that you would want as your friends. (It is wrong to isolate someone from friends he wants to keep.)
I don’t know that I would call those “deal-breakers” so much as red flags. Yes, that normally means deal-breaker, but the main thing is for our children to realize that discriminating on the basis of whether or not someone is a good match for us is not the same as judging them to be an inferior human being. Using intuition without any concrete idea of how to rationally discriminate between a good match and a bad one is not a good idea.
In my experience, a parent who even appears to presume to impose rules for finding a spouse on an adult child is also a red flag, however. You discuss the kinds of things that lead to problems, how to spot them and what you’re letting yourself in for, but if you act as if this is in any way your decision to make on behalf of your adult child, you’re on thin ice. (Not that the OP actually said otherwise, mind you.)
