These are definitely good goals. I think it's important to note too that working on yourself and things such as boundaries, self-worth, and self-advocacy are things that take time even in a relationship to develop.

For me, I've found that whatever romantic relationship I've been in I default to past patterns of self-sacrifice, withholding my own needs and feelings, and giving up much of myself to help care for the other person. That's even with breaks between relationships and also working with therapists.

It can take time to undo some of our past patterns. It takes commitment and it also takes self-compassion. Try to be kinder to yourself when you do fall into those patterns and also give yourself permission to grow over time. It's not an all-or-nothing process.

Good luck on this journey. You deserve happiness and love!
