which reasons would make you dump him?

That person being really immature. A relationship is a serious thing, not just a hobby or something to feel good, so a person must be mature to have a real relationship.

I would leave if he was cheating on me or abusing me in any way. I would also leave if I felt like he no longer respected me or loved me....there would be no point in trying to stay with him if the feeling just isn't there anymore. I would also possibly leave if I felt he was being too clingy or too dependent on me.

So much thought would have to go into ending a relationship because so much thought goes into beginning one. I would have to say that if the feeling just wasn't there anymore, it might just be time to move on.

Number one is cheating on me. I hate lies and infidelity. Among other reasons I would point taking me for granted, expecting me to do everything in the house, not loving me, not taking care of our child, not keeping his promises. As to supporting the family - a potential incapability would not be a reason to dump him because this must be an obligation for both of us and should not be a reason to break up.
