It was indeed a simple but interesting story to read.The story you wrote is actually something that we often observe in our real life.I also think that if a guy loves a girl then he should be strong and well determined to take the responsibility of the girl.But just like every other cases exception applies in here too.
Having a relationship and getting married is very different.So sometimes situation like this arises in the case of young couple.I don't know how old is the guy in your story because you haven't mentioned his age.
In order to get married a guy need to have a decent job,a place to stay and good financial condition to support his wife and the future children.So I won't say that it is always bad if someone says something like that.
It all depends on what he does,what is the present situation of his life,is he well established or is he just struggling to get established in life.A girl need to consider these facts before taking a decision about the guy.
