What would be a dealbreaker for you in a relationship?

Lying....
doesn't matter what its about.

Abuse. Physical or mental.

she's still married - or she has children

two timing me!

A very boring person

Cheating, lying, abuse, disrespect, and being too controlling or confining.

Basically the same things as Studentoflife said....but Ill also add neglect and lack of concern for my thoughts, feelings, desires, needs, etc. (So Id have to say selfishness or self-centeredness).

Lack of self-worth and self-respect.
Lack of communication.
No desire to improve the relationship.
Lack of respect for me.

Guys that say they wont consider dating a woman with childrren or will only put up with their partner sleeping with another man if they can watch and get their rocks off about it...
Which means that some of the guys that have actually replied to this question would definently be in that catagory....
Guys, come on now, your women is not a possesion to lend out to other men just so you can get your own jollies & thrills from it... and also why is it okay for men to sleep around and produce kids or to leave their wife and kids & date again, yet if a women has kids from a previous relationship then she is not worthy of being your partner BUT it is okay for a man to have kids and usually dump the full responsibility with his ex wife whilst he plays part time daddy and life goes on for him... I say a single women with kids can easily weed out good and bad potential partners just by that fact alone. As a good man will still give her a chance and an unworthy one will run a mile...
You know that women may have kids but she may have been loyal to her husband for their whole relationship and be kind and funny and works hard and is not only a great mum but a wonderful partner, but some guys cant see eyond the fact that she has kids from a past relationship....sad.

I agree with with FB. My thoughts exactly.

Bad hygiene.

Cheating or physcial abuse. Both are a big no no!!!!
