Is this normal ? I'm dying inside

Kayyyy
I broke up with my boyfriend because I felt like he was putting no effort into our relationship . I know he loves me and I know he wasn't cheating he just had a lot on his plate and I felt like I was supporting him in all aspects and getting nothing in return and I finally just had enough . He left for a few days I packed his stuff up for him and when he came to get it he asked if we could try to rebuild our relationship that he will stay at his moms to save money and take care of the things that have been stressing him out and that when we spend time together he will make the effort to be present and give me what I need and deserve . I was apprehensive because I still felt like he didn't want to hear my feelings and he didn't want to hear about how horrible he's made me feel the past 8 months . I stupidly kept texting him paragraphs about how he made me feel unappreciated and like I wasent enough . We were barely having sex and I just felt emotionally and mentally drained . He finally said fuck it and decided he was done and won't talk to me . His mom told me that I need to not try and contact him and give him a taste of his own medicine and make him realize what he's missing but I'm dying inside . I don't know if I feel this way because I know I beat a dead horse and kept pushing and pushing and he left and I feel like he dosent care or if this I just truly feel he is my person and I made a huge mistake . Does anyone have any advice for me I'm honestly struggling so much it's affecting my health and my work performance and I don't know what to do please help .
