Tips for quitting co sleeping

My daughter is almost 7 weeks old, I wasn’t planning on co sleeping with her because I know it’s dangerous. Anyways she only sleeps on my chest & if I put her in her bassinet with a shirt that has my smell on it she only sleeps for like 5-10 mins. I’ve also tried the shirt & playing a sound that sounds like a heartbeat. It worked for a good 10 mins then she woke up. Anyone have any tips?? Please I don’t want her to be 8 months old & still sleeping on my chest. Oh & I’ve tried moving her to right next to me on the bed when she’s dead asleep but she wakes up right away. 😩😩My boyfriend is mad at me for getting her used to it. It wasn’t my intention to co sleep I just fell asleep with her one night & ever since then she won’t sleep anywhere else
