Any man with that kind of negativity has full potential to ruin your life. It is better to dump such a guy rather than regretting marrying him.

Breaks Promises:
A little mistake or a sometimes forgetful mind can be excused and even a big promise, if broken once in a blue moon, can be forgiven too but if the frequency of promise breaking increases visibly then it is time for some cleaning and washing.

If he nods vigorously while making promises and easily breaks those only days later, it obviously means that he is making a fool out of you. That is not a good relationship to be in so reject that promise-breaker and find a keeper.

Hates Animals
Any guy who hates animals is an animal himself. He lacks empathy! Being allergic is a different thing but hating animals is out of the question.
