I've (29M) been in a relationship with my girlfriend (27F) for almost 9 years. About 5 years ago, we moved in together. We currently live in a condo that I own and pay the mortgage on. I also pay for water, waste, electric, internet, most of our food, vet visits for our dog, home and auto insurance, and other incidentals. Pretty much the only truly important shared living expense that my girlfriend pays for is our phone plan.
I don't mind this arrangement since I make a pretty good income, and have a strong desire to maintain my financial independence.
Over the past year, however, I've been feeling different kinds of discontentment with my relationship. Once specific thing I've pinpointed is the fact that I don't think I want to live with someone else. In my adult life, I haven't had the opportunity to really tailor a living space to how I want it. I understand that presenting this to my girlfriend would be essentially saying I want to break up which I don't feel is untrue, but I'm trying to focus on my more material concerns.
Despite that, I still care about her and love her and the problem I'm having is that, at this point, breaking up with her would put her in an extremely difficult position as there would now be all these costs and logistical challenges that she would need to figure out. I never wanted to be responsible for someone else, but I find myself in a situation where I am feeling responsible for someone else, and trapped because I don't want to ruin their life.
Any friend I would want to talk to about this is also a close friend of my girlfriend, and I wouldn't want to A: Force them to keep a secret on my behalf, or B: Impact their existing relationship with my girlfriend. If there's anyone who would want to chat about this with me, it would give me a great deal of comfort.
