get over him

i broke up with my boyfriend over a month ago and i can’t shake away the feeling that i want to get back together. he did unforgivable things that ruined our relationship and i could never trust him again, but i miss what we had and how he made me feel. i don’t know if i will ever find that again because we had something special even though it didn’t work out. i miss talking to him and laying next to him but i could never forgive myself if we got back together. i don’t know how to get rid of this feeling or how to get through this
