I don't think it is weird not to have your preferences defined; but it is necessary, in my opinion, to have your 'deal breaker' and 'must have' list in tact. These two lists help me to practice self-care, manage my irrational desires and as a result they hold me back from falling in love with the wrong person. Even if my emotions scream 'go for it', these lists help my mind to stay alert and be cautions.
I do not compromise my 'deal breaker' items (no alcohol/drugs, no unhealthy life style, no 'i want to be rich and successful' syndrome, no worldly ambitions, etc.). Again, these ‘deal breaker’ and ‘must have’ lists are my own guidelines and they are comprehensive and long but I don't want to share everything on these lists and offend anyone else. It is irrelevant anyways.
Well, you know my disclaimer: I have been single for over decade so you may want to listen to my insight with that in mind[emoji4] otherwise you may end up alone just like me and I do not wish that upon anyone.
