I would really appreciate any perspective you can offer. Thank you!

This month marks six years that my partner and I have been together. I'm 41, and he's 45. We moved quickly at the start of our relationship, jumping into a live-in job managing rental properties after knowing each other for only about a month. It was a wild experience, but it gave us valuable insights into how we handle stress, finances, and personal relationships during that time. Fast forward five years: my father passed away in September, just one day after he tried to initiate a discussion about how long our relationship might last. Then, just last night, while discussing a loan for a significant purchase, my partner made a remark suggesting I could take the loan with me if we were to break up. I’ve never had a strong desire for marriage, so I haven’t held any specific expectations, and I tend to live in the moment. I’ve been focusing on becoming more financially responsible and recently paid off some debt. However, I’m starting to feel a nagging curiosity that’s edging toward insecurity, and I want to address that before it becomes a bigger issue.
