Hey! I was in a similar situation after an abusive relationship. My partner forced me to be codependent, and it became a problem for me. I am now in a healthy relationship of almost two years with my fiancé. The biggest tip I can give you, is to slowly push yourself to begin doing things on your own, or be without, and ask for assurances when you need it! "Will you leave?" Or even "Will I be okay?" Lean on your partner. Another thing that really helped me was Journaling. When things became too overwhelming that I couldn't speak, it was so much easier to write down everything and share that with my partner. I also created a playlist on Spotify that was full of songs that would help me feel more comfortable and secure. I hope this helps!
