She called me today on my birthday

Backstory: Her (F31) and I (M35) shared a very intense 1 year relationship. We were both 1 year away from difficult long term relationships, had had issues at work (she was on mental health leave, I was not full time yet). We kind of became codependent in a way. We spent every moment together, went on crazy adventures travelling and hiking and just constantly cuddled and enjoyed our time together. She seemed very happy with how things were progressing.

I have a daughter from a previous relationship. She was ok with this as long as I wanted to start a family with me within a few years. I agreed. But she was extremely jealous of my ex. I am not in love with my ex at all whatsoever, but I understand why it hurts when you're dating someone with a child, and sometimes co-parenting situations arise where the two parents have to be somewhere, and she could not trust me to even be in the presence of my ex for the sake of my daughter. She had previously been cheated on, but I gave her zero reason not to trust me and she gave me an ultimatum. I went to a family dinner which included my ex (for the sake of my daughter) and she ended things then and there over the phone, went fully no contact, blocking and deleting me everywhere, 3 days before Christmas. It was very very difficult for me mental health wise, but I bear no ill will towards her. I understand how difficult and complex the situation is for her.

Anyways fast forward to today. I was at a bar watching the Canada-usa hockey game (we live in Vancouver). She calls me out of the blue, 2 months after not hearing from her at all. She said "I just can't stop thinking about you today because it's your birthday."

Im trying to act non-chalant but I'm very shocked. I didn't think I would hear from this woman again. I told her everything I've been doing in order to not get depressed (I've been doing a lot). Skiing, quit vaping, lost weight, got a new place, doing a pushups challenge ect. She seemed very happy and supportive.

Coincidencly to our breakup, a few days after Christmas her very ill grandma passed away, so I offered my condolences again (I had sent a card) and she said it had been a struggle. the situation that caused our breakup came up. I could hear the anger in her voice. I could still tell that she wasn't over it. She doesn't want to get back together and neither do I, we both recognize that we wanted different things from the relationship (I wasn't truly ready to move in and have more children, even if I thought I was)

Anyway. I still have some of her stuff. A custom blanket I had made for her for xmas that was delivered late. We made plans for coffee and so that I can give it to her.

What do you guys think? I have very mixed emotions. I still have a lot of feelings for her, but she also hurt me very badly by pulling the rug out from under me. Today really opened the wound I didn't expect it at all. I still think we aren't right for each other. But now I'm back in the spin cycle.
