The next aspect between Sun and Saturn is so far off that as far as the chart is concerned, it's a no. It's not even close enough to be considered an applying sextile yet.
The late degree ascendant, in my understanding, indicates that the matter is already decided or that it won't change. Saturn being ensconced in its own sign and favorite house--the isolated twelfth--also suggests that. It still seems to me that you're content, more or less, with singlehood. Or at least that you feel it's the best of your options right now. Maybe it's about wanting to shake off this clingy person. Saturn does NOT want to be clung to, and neither does Capricorn. You'd rather be on your own, doing your own thing, than with this person.
But you specifically asked about 2020, and as you pointed out, that's only two more months. So this chart is only telling us about the next two months. It doesn't apply beyond that. If the situation isn't going to change within the next two months, it can still change anytime after that.
But if I'm reading it right, you still have an out right now: you can focus on doing your own thing, whatever that is, and make it clear to Clingy that you are Not Interested. If what you're really looking for is a good excuse to shake him off, you don't need a boyfriend for that. Your own word should be enough. Probably will be: Saturn is domiciled in this chart, while Sun is peregrine. That gives Saturn more strength.
If you really want a boyfriend too, then there will come a time when conditions are better for finding one. It just doesn't seem to be that soon.
