The best way to tell your parents is to show them that you understand the importance of getting engaged. This means you should have a plan as to when you will be getting married, where you will live, how you will support yourselves, if you will continue school and what kind of jobs you both will have. If you can answer all these important questions and have a good plan for your future then you will show your parents that both of you are mature and responsible enough to get engaged.
Just tell him
just tell them right out....I want a baby with you
You just tell him
You be honest with them and tell them that you don't want them taking you boyfriend. And you can also tell your boyfriend your feelings on the matter to show trust to them. Hopefully he will also be able to help out.
He is your boyfriend, So just tell him that you don't want to hang out with him. He should understand.
You can just tell him what the tradition is like any other. If your telling him this to dictate about the two of you getting engaged, that's a no-no, you should want him to do it out of love for you freely and you should want him to ask you freely. Nothing screams pressure more then this.
tell him you want him back!
By marrying him.
Tell Him
Just tell him.
Tell him you miss him.
Unfortunately you have to simply tell him you have a boyfriend and are not interested in him that way.
