I (F26) have been with my boyfriend (M26) for 8 years, we started dating at the end of highschool, and I really see a life with him. We just moved in together last year.

It's been tough for us to move forward, with housing costs, tuition, debt, etc. We both lived in houses of about 3-4 roommates, and i've been working since I got my masters while he works part time and completes his.

We talked about how once we have money we will get married, which is something I've wanted much sooner. I don't need a wedding that costs $1, or even a ring. But he says if he wants to marry me, he wants to do it right, so I've waited.

This is all context for whats happened...

A little while ago, my grandmother passed away. She left almost her entire bank account to me, her only granddaughter which I knew would happened, but not so soon. My parents got all the property, etc.
Now my parents are wealthy but they always said I have to make my own way, so I never got any finanical aid from them, from my first car, to rent, to tuition which I agree with. So this amount of money is really a game changer for me.

When I got the money I went to the bank and talked to a finance person and set up things like IRA, investment all the stuff including paying off my debt. But left a lot of money left over for now, to decide later. What I want to do is (some fun unrelevant stuff) but mostly purchase a small older home and rent it out in the college area. I could do so without any mortgage and start generating income, and easily move me and my boyfriend into a nicer place.

He was upset at this idea, and said I was selfish, that I never offered him any money, specifically didin't pay off his debt and finish his tuition costs. I told him that i'd be covering a lot of other things allowing him to pay his tuition, like moving us into a closer place to the college, paying for the rent, and generating income to really help him save every penny from his job. He told me that it's not enough and if he were in my shoes he would have paid off both our tuitions. I told him that if I paid his tuition I couldn't afford another property anymore.

Anyways, we went back and forth and it ended up with the argument going to yelling, and finishing me saying if we have the money why has he not brought up marriage, and he said why would he marry someone who wouldnt help him.

Now we aren't really talking, and i'm not sure if I am an asshole, and should pay off his debt for him.

If you are curious the amount I recieved was around 600k USD.
