I agree with Zen. Although guys (and girls) will always make mistakes, say things without thinking, and do things they regret later.... it's typically the first reaction that lets you know how the person really feels. And if you get a consistent first reaction of "I don't care about you" then I think you have your answer.

You can always find another man. Especially if this one doesn't respect you or treat you right. Love should be unconditional.

I used to be with a guy and I quit smoking and then asked him "if I picked it up again would you want me to tell you or not?" and he said he would rather not know because he didn't want to think about it. Then one day he smelled smoke on me and flipped even after I said "you told me not to say a word about it". Turns out that he was more interested in simply having control over my actions.

Good luck with everything.
