if infinite means growing quicker than you can measure then yes infinite is possible.
if it is growing then i see (without fact) that its a spiral growth
if its finite that would mean an overlap which kinda makes it infinite..
or an finite inward spiral..
i kinda feel that there's at least 3.or 3 parts to 1
all guess work and my thoughts on the question.

My thoughts are more along the line of infinite 3D spirals of infinite size in either direction...if you can get your head around that!
Can someone show me how to express that mathematically??

p.s. by "3D SPIRAL" I mean a spherical spiral with the diminishing point at the centre and all other infinite spirals having the same common diminishing point

It is useful to qualify the term to avoid ambiguity, will the universe last for an infinite time or is space of infinite size at any particular time. I'll assume you are asking about the latter.

if infinite means growing quicker than you can measure then yes infinite is possible.

It does not mean that, it means that that no matter how far you travel, you will not find yourself in a region you have already traversed.

if it is growing then i see (without fact) that its a spiral growth

The expansion of the universe is a linear scaling, it grows in all directions at the same rate (currently roughly 1% per 200 million years).

if its finite that would mean an overlap which kinda makes it infinite..

It would wrap round so you start passing through regions you have already seen.
