what is wrong with me?

alright so a little back story. i used to fw this guy (february-april) who is THE perfect guy but i literally hated myself. i was so insecure so i had to let him go and fall in love with myself. i finally fell in love with myself over the summer. i was single and haven’t fw anybody since him. i‘m happy being single. i’m very happy by myself. i’m a lonesome person anyways. i don’t mind it. i was enjoying the time spent getting to know myself.

well he came back into my life (around november) and told me that he still wants me. i was afraid i had missed the opportunity so i was stoked that he still wanted me. well i was waiting just until it felt really right to tell him that i wanted to try us again. but we’ve been texting since every single day all day. i wanted him so badly, thought about him constantly, knew he was for me. a few days ago i got the feeling. so i drove to him at 2am and told him how i felt. and now we are like together. but all the sudden i just don’t want it anymore. what is wrong with me??? am i broken? am i meant to be single? like i am very happy being alone but i also really liked him. he’s literally the perfect guy. everything i could ever ask for in a man. but now it doesn’t feel right. what is going on? am i dumb or what??? any explanation? please
