Question: What do I call this verb stem?

[conlanger]

I have a verb stem in Akachenti that gets used by itself for a variation on present indicative which indicates that this situation/action will continue in the future, e.g. I love you now and expect to keep on doing so.

With a non-present marker, the stem is used to indicate simple future tense, e.g. I will come to love you.

The normal present is the unmarked stem and indicates the action began previously and also occurs now. You could call it a present perfect or a present continuative, e.g. I’ve been loving you, I still love you, etc.

With a non-present marker, the unmarked stem is used to indicate past discontinuous, e.g. I loved you, but now I don’t. To me, the unmarked stem is clearly indicative.

That said, I’ve tried calling this future stem optative, subjunctive, and irrealis, but none of them quite fit. What do I call this thing???
