Relationship

so my boyfriend and i recently took a break that eventually led to us breaking up. We didn’t leave on bad terms at all, i had to much stress going on and he said he wasn’t feeling like himself anymore and unhappy. I texted him out of the blue and texted him i love you and he said he didn’t know what to say and that ripped my heart into a million pieces. I felt so heart broken. I don’t know what i should do ? Should i just let time play it’s role ? if anything were to ever happen again between us ?
