Welcome back Lily, and thanks for sharing your personal journey with us.
Sorry to hear that things didn't work out between you and your ex. From what little I knew it sounded like you were quite hopeful for the future, but it seems like you made the right decision to move on. It can't have been easy. Relationships certainly aren't smooth sailing, but neither should they be a chore and make you feel emotionally drained. Hopefully with time, you will be able to look back fondly on the happier memories you both shared together.
Definitely a good sign that you have met someone who is a more positive influence in your life. I find positivity breeds more positivity, so the fact that you are getting your personal life back on track is a good sign that things will eventually look up in your professional life too. I'm sure you will find a good opening to your career soon, and your are being sensible in using a temp job to keep things going in meantime.
Hope you will continue to contribute to the forum
