It seemed that love is strong, but
individualism is
stronger.
In marriage, it is a mixture of mutual strength, the power of
compromising and the dissolving of personal ego that breeds
individualism. Your relationship stays because love retains your
heart, but that doesn't mean marriage could follow. Personality
conflicts rain heavily on your relationship - you need break those
harden soul and blend the lighter substances into the soft interior
of your BGR.
As again, for those break-patch relationship, C|oUdiSm remix III
states that the relationship usually dies after the second break.
(This is modify by reasons of coming together, time taken and other
factors). Often, in relationship, we delay the inevitable and hope
that things will change. However history simply repeats itself -
coming together just to split again. Holding on to things we ought
to let go in the past.
Not true? 
We have been together for 2 yrs plus and still we are
communicating like that.
Getting a house will generate greater problem. Your child-like
relationship is not ready for such additional burden to your
relationship. Imagine a small boat trying to hold more loads - it
would sink faster than you could think.
P.S: There is a serious need to review your
relationship. If it has to end this time, there is
NO need to patch again in the future. Understand
that temporary trying to sever a relationship, to think that you
could avoid/solve current problems, only serve to kill your
relationship without you consciously knowing. This is called
Cumulative Effect under CloUdiSm.
Even if you want to repair your relationship, you wouldn't even
know where to start. Too many holes everywhere. 
Cheers
