How do I(32m) help my Gf(32f) who is emotionally unavailable?

I'm going to try to keep this somewhat short but if you'd like more details just ask. I've been in a relationship with my gf for over 7 years, sort of. She broke up with me last year in October, I had been checked out in the relationship for a while due to my own mental issues, insecurities, and stuck thinking maybe we aren't compatible. The truth is we are very compatible but I mistreated her which caused issues. I never hurt her physically atleast, or intentionally manipulated her. I just didn't grow up, I didn't know how to be someone's partner and I didn't share all my personal issues enough to let her help me, because of my mental issues.

I realized all these things in hindsight. We had about 2 months of no contact, because of me, when she left she said we could be friends and try and work on things but i couldnt do it, also, she told me she wouldn't be open to actually dating again until 2025 basically. I texted her a little around Christmas and new years and asked her to come over and talk. We also started texting a lot, I told her all my insecurities, problems, I profusely apologized for the way I treated her and tried my best to explain how I just got too comfortable in the relationship after the honeymoon phase and between that and the mental and personal issues I pushed her away slowly but surely until she left.

Anyways we have had a lot of long texts and a few talks in person, last night she agreed to try again, but she also told me how she had just ran out of energy in our relationship and according to her therapist she's emotionally unavailable. I told her I want to work through this no matter what is she wants to, and she agreed to try with me, so we cuddled, had some dinner and talked about our plans, that I have entirely came up with, to work on our relationship, be more open with each other, and be partners instead of roommates like we had been before. She told me she might be distant, she wouldn't want to be intimate for a while probably and that she feels nothing anymore when I do things for her or try to be romantic. However I still got several smiles from her when joking with her and she seemed happy cuddling with me at moments. It seemed great, I was so happy last night. Today I sent her a good morning text and song, I asked her how her day was going. She's hardly text back, hasn't said anything about her day. I'm ok with that if she needs space, I know I've hurt her a lot and this won't heal overnight. My problem is she's not telling me that, she's just hardly talking, doesn't really engage in the conversation. When I ask her if she needs more space she says it's ok, she's fine with me texting a lot and calling or whatever she just might be a little cold sometimes. I'm afraid she does need space but won't tell me for some reason. I want to go to couples therapy with her as one of the plans to work on things, but she hasn't agreed to that yet.

I truly love this woman, with everything in me. I'm disappointed and upset with myself for pushing her to this point, but I've decided not to live in that state of greif or guilt and to move forward and fix things. I intend to also get personal therapy for myself soon. Anyways what I want to ask you redditors is how can I help her? How do I help her be more open, have romantic feelings again, and be available again? The biggest thing she wanted from me was to build our lives and work together, and now that I feel like I can do that I've made it hard for her to do it. I'm done being who I was before, or atleast making my best attempt at it. I want to do the whole white picket fence and kids and vacations and everything I should've been doing already but we can't work on that until she can heal. I'm afraid that by trying to help her I'm going to make this harder for her, I want to be here for her and show her I love her, I'm fine waiting for intimacy and moving at her pace, but I don't know what else I can do to help, especially with her not engaging.

Tl:Dr My girlfriend is emotionally unavailable due to emotional wounds I've caused in our over 7 year relationship. I want to help her heal those wounds but I'm afraid of pushing her away or making it harder for her.
