Plentyoffish dating forums are a place to meet singles and get dating advice or share dating experiences etc. Hopefully you will all have fun meeting singles and try out this online dating thing... Remember that we are the largest free online dating service, so you will never have to pay a dime to meet your soulmate.
Some things you can ask, some you can observe, but some of the latter may take a lot of time to find out. That caveat stated, deal breakers for me include:
smoking heavy drinking fundamentalist anything lack of compassion or kindness rudeness inconsiderate entitlement unresolved issues unhealthy attachments lying, cheating, stealing uninformed or lack of curiosity lack of spontaneity
Can we just simplify things, and they can email me the list of questions beforehand so I can fill it out... I sooo hate taking tests while someone is staring at me timing me.
Besides, it'd give me a chance to 'throw it out' and say next without having to go meet them and go through a torturous '20 questions' interview process, especially if they want to bring out the bright light, and start demanding answers to their questions.
Seriously, I just go with the flow of the conversation, and see how they react and the impression I get as the conversation flows. You'll get a lot more 'honest' idea of someone from comfortable/open/relaxed conversation than you will by firing off a list of questions at them making them feel like they're being interrogated by an SS officer.
