If you are feeling isolated now, with your friends avoiding you, I can only imagine that being 17 and a stay-at-home mom would be even more isolating. If you do stay at home, you may end up entirely psychologically and financially dependent on your fiance. Will that be good for you? When do you intend to get married? You have no legal protection financially if you’re not married.
The question is really, can you afford to stay home? If you do work, can you afford to work? Are you able to earn enough money to cover the childcare costs associated with working? Do you plan on going to college or taking some sort of vocational training while you are home with the baby?
From some of your posts, it sounds like he may have some control issues, and you may be setting yourself up for a situation that is not healthy for you if you don’t have some independence. If I were 17, pregnant, unmarried, financially and psychologically dependent on another person, I would be extremely worried about my future. Your child is going to be financially dependent upon you for the next 18 years. If something happens with this relationship, and decide to walk or need to walk away from the relationship, how will you be able to take care of your child if you have no education, work experience or self-reliance to fall back on?
Life experience teaches “prepare for the worst, hope for the best.” You always need to have a Plan B, even if you don’t use it. Statistically, the odds are against this relationship working out for you. The divorce rate for people who marry in their teens is 48%, compared to 24% after age 25 (CDC statistics). None of those 48% go into it thinking it’s not going to work out.
