Not sure which so if you feel I'm an asshole, please tell me. Title sounds really bad because I feel really bad about it.

So I (40M), have a daughter with this woman (31F). We aren't together because of reasons that almost drove me to kill myself. That didn't happen for better or worse. During lockdown we got back in contact and slowly started building back a relationship. I was on and off speaking with her during the years we were not together. She told me that she has decided that maybe it would be best if we got back together since she saw me as the best of those who were asking her out. She said she would give me time to build my wrecked finances, that one was caused by my not being in a good place mentally. She said she'd give me three years. So I said great, I'd still do my best to give to her and our kid. The kid doesn't know I'm her dad btw. I promised to give her 80k of our currency to help in building a home for her and her kids, she'd put in money into the house as well. She ended up pressuring me on money. That I wasn't giving enough. That we should not be together after all. She even said she was just using me (maybe a heat of the moment thing and not true, I don't know). Right now I'm not speaking with her. Thing is, that house would help out my kid a lot when she grows up. But I feel like I'm nothing more than an ATM. AITA for wanting to back out of that verbal agreement? Should I even still pursue this or should I just go my own solo way?
