I’m losing my mind ..

Lele

I need help . I may sound stupid but I’m putting my feelings out there so be nice to me . I’m still young living in a very fucked up household . I have no friends and no family . The only person I had was my ex . We were dating for 3 almost 4 years . That entire time he taught me plenty of things I needed to be taught . He was there for me when ever my mom kicked me out and put me on the streets . He was there for me through everything and I was there for him . He lived with me and my mom and she made him pay rent but I would pay it cause he had other bills . I was the one who paid for food for us to eat since my mom didn’t go grocery shopping . I paid for everything so that he didn’t have too . His mom was fucked up to him too . I was emotionally there for him for that too . Recently tho I think my household has gotten to him . My cousins have been coming in our room taking his stuff and my mom kicks him out like she does me . They are very toxic and if you are a person like me when you grow up around that it’s just normal to you . He said he wanted to focus on himself as get his own place so he broke up with me . But then at the same time he’s texting his ex . and I asked him and he says they are together . It’s only been like 2 days . Idk I’m losing my mind and I don’t know what to do . Like I said me and him have been through a lot . And right now he’s at her house . I don’t know how to feel . He is telling me that he’s not going anywhere and that he will always be there for me and how nothing is going to change but it did . EVERYTHING CHANGED and I don’t know what to do ..
