Olive, we can love someone even though they choose a different life path than ours where a marriage partnership will not work out. The choice your boyfriend is asking you to make is a hard one considering that you would like to have children at some point and you really can't say wanting children and having a family will change.

Also, you have talked about not being happy with the career choice you have made, well, you are still young enough to make a change with that too as you may need additional education to get where you want to be. You are learning from "doing" right now and even though you have individuals who have strong opinions about what choices you "should" make? You need to learn how to make your "own" choices so you don't look back on your life some day wishing you had made your own choices. After all, it is "your" life.
