Mii losing interests

I have an mii lookalike of my partner and the mii has been losing interests on their special someone and my married lookalike (theyre best friends). Their special someone mii status changed in "only in love" and my married mii to "trusts a little" . Even though their special someone still bonds with her i still feel like if i ignore this too much i might see her breaking up with them off-screen. What should i do?
