How to talk to your boyfriend about marriage?

Start off slow,gradually get to a point where you think it would be a good time to pop in that cheeky suggestion ;)

Be discret don't directly say you want to get married try to talk to him about the future your future and why you see them together one day

Treat him to something nice like sex or a nice dinner then be like I think I would to... and don't forget to mention all the great memories.

If getting right to the point freaks you out a bit, then try to start a more general conversation on the topic. If you have a friend who got recently engaged, by the way, don't be afraid to casually bring it up — talk about how old they are, how long they were together before getting engaged. You may be able to at least gauge their interest in marriage or their general feelings about marriage. This is a wise move if you think your boyfriend or girlfriend might have some negative feelings about marriage and you want to avoid an awkward, direct conversation.

Let him know how far you all have made it in life and how challenging it has been and that you believe that finally he is the one. Let him know that you're happy with him and you plan to spend the rest of your life with him

You have to just let him know that at some point in your life you see yourself married with children, and if he does not want to be married you can ask why but if marriage is something important to you then you will have to let him go and move on.

Bake a ring cake and propose in style!! If you want it, go for it!! You won't know if that's what he wants unless someone takes that first step so why don't you do it?

I do not have a boyfriend, but, I would not press the issue unless he did. Then, I would be completely honest and upfront with him about how I feel.

You can start by talkin about a mutual nice couple and how you wish that you have a future like them

Call me old-fashioned etc but I believe a guy who is serious with you will come up with that topic first.
