Til death do us part is marriage not relationship...

its sad that he feels that way.

Why buy the cow when you can get the milk for free?

I guess I'm not surprised the number of people saying what' the big deal, just disappointed. There's a reason gays are fighting tooth and nail for the right to get married. For $50 in most areas you can get a whole mess of legal rights in one easy place. My cousin wasn't married to his girlfriend, the mother of his child. When the 3 of them were killed together in a car accident her parents buried her and the child before even telling his parents. Asinine yes but the only reason they could do that is the police had no idea who he was, it was her car and they weren't married. If the child had survived my aunt would have to fight legally for visitation rights. She said she was told if only the mother hand been killed he would have had to prove paternity before being able to visit the child in the hospital because in their state next of kin would have been the mother's parents and they could have blocked his visits. Hospital visitation rights, parental rights, rights in case of untimely death: these are all built into the marriage license. And if it doesn't work and you can do an amicable divorce then you pay like $400. Balance that against trying to do a 2 person mortgage, file school paperwork if you have kids or heaven forbid one of you loses a job or in one way or another needs to go on the other's insurance.

Explain to him that you want to make it official

He's saying you're a faithful partner in a very poorly way

Time to prove him wrong. Dump his ass now. He's not going to just change his mind later. If you want to be married someday it won't be with him. Seriously, move on and fast.

Break up with him just to shake things up a bit! Lol

He clearly doesn't understand the concept of marriage- you don't do it to stop the other person from leaving. You do it because you never want to leave them. 6 years is a long time, so it's a tough situation, but if he doesn't see the flaw in his reasoning you might want to re-evaluate your entire relationship. This statement, to me anyway, sets off a lot of alarms.

You should propose to him, sense he ain't going to do it.
