Coming from a psychological standpoint, it is nothing but normal that you did so. You were both so in love before this and you can’t expect yourself to just not care at all. Nobody should tell you what you really or shouldn’t do after a break up. We all deal with break ups differently. If this is the first step for you to take after the break up, then take that first step. Most importantly, the grief comes in waves. Therefore, if it comes, allow yourself to feel it entirely instead of numbing it. Most people chose to numb themselves. It isn’t healthy. You wanna cry it out? Go ahead. You feel like drinking the sorrows away? Do it, but in moderation.
If you need a listening ear, I’m more than happy to offer it to you. Remember, your feelings are valid. ☺️
