It means the same, but with two different implications, for those who are too particular about language.

ex-boyfriend = It is history now, he used to be, just stating a mere, absolute fact

“then-boyfriend” = used when we mention him in sorrow and regret. It could also imply an eventful history.

Then-boyfriend is for when you are speaking of a time in the past, and the boyfriend/girlfriend at that time is mentioned. This could be because you have furthered the relationship, marriage, or you have broken up and may still be friends, or not. The latter is the most common. You can also say, my boyfriend/girlfriend at the time.

I was in Paris with my then-girlfriend Chris, when we….

It’s the same as ex-boyfriend.

What a wonderful question. Religion is, of course, the form that one’s worship takes. Thus there are thousands of forms. Religion includes a system of religious beliefs and practices. The object of the religion may be false gods or the true God. Hence, there is false religion and there is true. Religion can get very fancy or remain simple. In the former case, such as it is today. In the latter case, such as it was in the Garden of Eden. What then is worship to me? How do I worship? To worship means to obey. And to obey means to worship. The two are intimately connected; indeed, they are coterminous and cannot be separated. Specifically, to obey the Sovereign Lord God Jehovah of Armies is to worship Him. I do my imperfect best in this regard. I fall on my face and get back up to try and try again. In the Garden of Eden, so long as they obeyed Jehovah, Adam and Eve were worshiping him. No temple, no Mosaic Law, no meetings. Simply leave the tree of the knowledge of good and bad alone. Simple. The minute they disobeyed, they stopped worshiping Jehovah. Same with the nation of Israel. The minute they attempted to practice a syncretistic religion they stopped worshiping Jehovah. The minute they made the golden calf, they stopped. And on and on. To worship is to obey. To obey is to worship. Hannah J Paul

It means boyfriend at the time of…. Ex: Last year my then-boyfriend gave me a necklace for Christmas.

It means the boyfriend at the time of when the story or event took place

Yes, same as ex-boyfriend.

this is what a person would say when they are talking about someone they were dating in the past. it is not someone they are dating now.

like for example: I went to Cedar Point two years ago. My then-boyfriend, Jeff, went with me.

This indicates that the person in the sentence is no longer dating Jeff.

The then boyfriend is the same as the boyfriend then. Doncha jus luv English?

-MM
