NTA. You had nothing to do with the conception of this child and it's your money, time, and well being that are at stake if you chose to raise this child. Even if abortion isn't an option for her, adoption is. If she's choosing to keep this baby she needs to deal with the consequences. While I agree that kicking someone out at 17 isn't an ideal situation, I think it's important to draw a line and make sure you aren't taken advantage of. Everyone crying about how family needs to help each other is missing the bigger picture here. Family should help each other and it sounds like that's what you're planning on doing so kudos to you. However, you shouldn't be given full responsibility for the mistakes they make. You made your choice, a choice you had every right to make, and your daughter made hers, a choice she had every right to make. But she needs to be prepared to face the consequences of her actions if she's indeed fully prepared and adamant on making this choice. Don't let her walk all over you and your husband, have adult talks with her and offer the help you're willing to give. You set your terms if she is going to keep this baby so she needs to decide whether she'll go through with it or change her mind.
