attached too quickly to him

me and my ex have been talking recently and we both told that we miss each other. we broke up mutually just because the time wasn’t right and we weren’t communicating very well. anyways he told me isn’t ready to get back together and he doesn’t know really when he will be. i think i have attachment issues because i can’t stop thinking about him and it feels like it would for me if we were dating. like i love him so much but i feel like if i show that i even think about him then he will think it’s too much. i’m like literally crying writing this... 😓
