While it may not have been the most desirable suggestion, it was one meant well. And I might add, it's not the worst suggestion in the world. Sometimes people can't handle that type of situation very well. And I'm not saying Vampy is or isn't one of those type of people. But there was no harm in mentioning adoption as a viable option. Amy didn't say "Do it, you horrible mother!" She just asked that Vampy consider the idea. And I think anyone in a tough situation should consider ALL possible solutions, difficult ones included.
Having said that... Vampy, assuming you're not keen on the adoption idea, your next best bet is, as many others have mentioned, a shelter. If your husband is a useless and/or abusive bum, get out. Period.
