I don't think anyone but your husband can tell you what his comment means so you need to try and get him to open up to you. Maybe he doesn't understand what it means fully himself. It all depends on what is causing these thoughts in the first place, how deep it goes and how long these thoughts have been there. If the person saying these things has thought long and hard and cannot see a life that they are happy with ever occuring then there is good reason for concern. I will say this though, personally i think suicide is only selfish depending on the circumstances. If someone is truely miserable, has been for a long time and is absolutely confident that there is no way out and things are going to remain the same or get worse then i really do understand it. Obviously it is hard on family and friends but think just how hard it is on the individual who is thinking about or commits that act. If i were you i wouldn't be telling people about this without your husbands permission and i would try to comfort him and try to get to the bottom of this, you have to be careful as sometimes suicide can be an impulsive thing and deep down that person doesn't really want it. When thats the case, i can see where you are coming from with the selfish thing. People are different sometimes you can have two individuals with the same life, one hates it and the other loves it, its hard for the lover to understand the hater because they are happy with life. Humans are complex, understanding that we are all different and content with different things could be the key to a happier future.
