My boyfriend has been with me for 3 years and still hasn’t proposed to me. Why?

He may not wanna go there. Youll have to ask him how he feels about it

He is not attracted to you.

He might not be ready yet. I've known couples who've gone like 9 years before they decide to propose. 

Is there a need? Why buy the cow when you get the milk for free?

Because he is SMART? He doesn't want KIDS? We only date people to determine the suitability of that person to be a MATE and a PARENT. It is the PRELUDE to MARRIAGE. There is NO OTHER reason to date...when push comes to shove.

Marriage is an agreement between a man and a woman to START A FAMILY and RAISE CHILDREN. No wanta the KIDS?!?! NEVER EVER GET MARRIED!!!!

I am not saying you CAN'T get married...but there is NO POINT. Marriage and children go together.

Did you have the 1st date discussion? "I would like to have kids in the future"? question EVER COME UP? HMMM???

And HOW OLD are you? If you are both closing in on 30...then it might be a good time to "consider" marriage and children....BEFORE THAT?!?! NO!!!!!

Perhaps he wants you just for sex.

He isn't interest in marriage 

Maybe you're a bytch

Because he does not want to. Why buy a cow if the milk is gratis. Set him an ultimatum.........marriage or the curb.

Peace.

Why buy the cow when you're getting the milk for free?

Maybe he doesn't know you want to get married.  Many people stay unmarried these days.
