Am I being led on?

Hello I need some advice please I have been with boyfriend for almost 4 years and were not engaged we live together both have been married before have kids between us have a great life except not married. I am wondering if it will ever happen..2 years ago he took me out and we looked at rings and even had bride magazine ....and a pretty dress that now hangs in the back of closet. Last year I bought us a house and we got in a fight after because it had been bugging me still no ring...he said he had been saving money and with house that it took away from money. I paid the down payment myself..then I just dropped subject.... This past Christmas 2 close friends got engaged and it made me happy but sad... I feel like what is wrong with me why doesn't he ask?? We don't talk about it ever anymore...and 2 weeks ago he surprised me with a vacation.. Said he's been saving for months..I was happy but at same time what happened to ring money and his big proposal?? I don't get it....last night someone asked us are u ever getting married?? I quickly said no...he just looked at me weird and said I dunno...and the friend said why not ...I looked at him and said those things have an expiration date u know kind of jokingly... He just kept eating his food and that was that.. He didn't talk to me later about it or anything...what am I supposed to think?? He says things like be with me forever...but then I feel like I'm being lead on here...if u didn't want to marry me why lie and say u had a plan and all that and spend the money on a trip...this is driving me a little crazy and making a problem for me..I don't bring it up I don't wanna marry someone who I feel would only be asking cause I wanted it what should I do??

Why do you need to be married if it is fine as it is? Over half the married couples are so miserable they divorce and more are just miserable. He does not want to marry. Maybe the two of you need to talk and get this straight. You need to be on the same page.
