I really hate to be one of the few.... but growing, and getting louder, voices of reason here...
But, OP, this does not sound right to me at all...
HE gets his place.
HE gets you helping to buy everything.
He doesn't seem to be exhibiting any 'patience'.
HE gets to agree to the whole 'yeah sure... ONE DAY'.
It's all so easy for him...
You, on the other hand, get to sit in limbo.
You get to help him get established in his own place.
You get to look forward to sitting and waiting until, maybe, ONE DAY.
He is holding all the power and playing all the cards here.
I would NOT be going in on ANYTHING until you had that marriage license.
At this point, you don't even have a ring on your finger.
If you get further financially and legally intertwined with this man, without any ring, any commitment, etc... You MUST, at the very least, be honest with yourself here.
Maybe he DOES want to get married.
Maybe he has some big romantic idea to propose over Christmas or something?????
Maybe everything is working out ALL for the best.
We do not know his intentions... and I would not presume to make any judgment call on that.
( I will only say that based on what I am reading here, I would have concerns and doubts. )
But, my advice to you is just this.... Until you have that ring on your finger, and have gone and gotten that marriage license... I would not be planning any big wedding, worrying about 'JUNE', buying any furniture, or anything else... AT ALL.
Maybe he is wanting you to be patient.
If that is the case, and you are completely comfortable with the status -quo, then great!!!! But what I am seeing here is you, giving and giving and pushing and pushing... That is not my understanding of the word 'patient'.
But, be honest with yourself here.
Buying furniture, booking wedding venues, etc... BEFORE you have that ring is just not the way to go about things. Yes, that might sound simple. But, you know, IMHO, it really is that simple.
