24M & 37F: Engaged, Dumped, and Mid-Home Purchase—Move In as Her Roommate or Go Solo?

I need some honest advice. I was engaged to my fiancée for 60 days, and have been dating 13 months (24M & 37F), and we were deep into buying a house together. But 10 days ago, she broke up with me. A few days later, she called the mortgage company and had her name removed from the loan, leaving me to decide if I should go through with the purchase alone. Financially, I could afford it, but it wouldn’t put me in the best place right now.

Things were good before I moved in with her in January. I still want to make things work, but she’s told me she doesn’t want that, at least right now. I told her I’d do whatever it takes to be better, and I’m starting therapy. Her biggest issue with me was being too controlling—like buying her clothes and getting upset if she didn’t wear them all the time. That’s just one example. I know I had other flaws, and I’m trying to grow.

I was also still adjusting to life with her daughters (14 & 2), and I’ve gotten really attached to them. We had great family moments, but I wasn’t always in the best mood on outings, which caused tension.

To complicate things further, I moved out of my apartment a month ago to move in with her and have been sleeping on her couch since she’s broken up with me. Now, she’s buying her own house and offered for me to move in as a roommate if we can “just be friends”.

So, my options:

Move in with her as a roommate – I’d stay close to her and the kids, but I don’t know if it would help or hurt me emotionally.

Buy the house alone – It’s a big financial step, I could afford it alone, but it wouldn’t put me in the best place financially at the moment.

Has anyone been in a similar situation? Any advice on whether I should hold onto hope or focus on moving forward? I’m struggling to balance my hope for reconciliation with the need to establish my own well-being.
