Most Helpful Guy
Look strongly at the reasons for breaking up. Were you completely happy in your relationship with that person? Outside of that, you have to really consider his actions during your time together, along with his excuses for breaking up with you.
Personally, if my ex split with me because of a fear of commitment or because she lost passion, then I'd assume she's just feeling lonely and things would be great at first, only for her to realize she wasn't really in love with me, but was in lust with me, not wanting to be alone.
I understand you have feelings for this person, but just be aware he is very likely to break your heart again, and maybe again, due to the same stupid excuses he gave you the first time around.
