Does it matter? Which (stay or go) are you looking for reasons/rationale/justification/permission (the last of which you don't need) to do? Some issues (e.g. violence) are pretty clear-cut; if you're in danger of personal injury or loss of life, you get out—period. Is this a situation like that? If his behavior(s)—whatever they are/may be—put you at personal risk (physically, emotionally, psychologically, financially), then IMO you are justified in getting out—or putting some distance/buffer between you at the very least.

Other issues may be... grayer. In those cases, it may be helpful to get someplace safe where you can take some time to take a step back to think clearly & evaluate the situation. If it helps (and it often does), write out the pros & cons of the current situation AND likely/possible futures/outcomes. Are you equipped (education, experience, temperament, psychologically, emotionally, etc., etc., etc.) to handle this? What are your future expectations?

What if the situation were reversed? Not how would you WANT the other person to react/deal with these issues, but how would you reasonably EXPECT the other person to deal/react/FEEL? How would a REASONABLE person (re)act in your situation?

But bottom line: What are your emotional feelings about Tito? Is it love, guilt, both, something else?

Of course none of these questions need answers here—only in your own mind—which makes complete candor/honesty all the more important.

Best wishes,
