Is this the right time for me to break up with my first long-term partner?

I’ve (22F) been dating my first long-term boyfriend (24M) for almost four years now. We’ve been living together for the past year after I graduated from uni nearly 2 hour drive from our families (because of the location of his new job). There’s nothing fundamentally wrong in the relationship, yes we have arguments every now and again, but no real fights that go on longer than a day. I just don’t think I love him anymore. We don’t have as much fun as we used to, he’s really not spontaneous or adventurous like I’d like us to be, our values and opinions on most things are often very different. There’s lots of things that aren’t as they should be but the bottom line is that for a while (perhaps a year) I know deep down he’s not the man I want to marry and have a family with. I’ve expressed concerns over the last couple of months about our relationship because I know he’s not totally happy either. I know I can’t change him and wouldn’t want to force him to change how he is. I feel like I’m delaying the inevitable (breaking up with him). There’s nothing catastrophically wrong, I just don’t think we’re meant to be. Plus I have a real desire to go off, live on my own for the first time, start rebuilding my confidence and identity as I’ve always overly depended on him.

Anyway, this has come to a head because we have handed the notice in to end our tenancy at our flat next month. We are in the process of applying for a new tenancy in a place I’ll be closer to family. The difficulty is, in the back of my head, I know we will most likely break up eventually (if I have any ounce of self-esteem left, ha) but we’ll be tied in to this new flat for 6 months together minimum. I don’t want to sign the agreement and realise it’s unbearable within a few months because then I’ll be stuck paying my share of the rent still (I would be going back to live with my parents). But then the biggest problem is that he will have to find somewhere to rent by himself- this would have to be in a shared house as he’s only just started out in his career. Time is ticking by and I need to commit to a decision.

I don’t know what to do- should I wait it out? Should I listen to my intuition? Does anyone have similar experiences of breaking up without a massive argument or problem in the relationship? Thanks for any help x

TL;DR! I have lost interest in my 4-year partner over the last year. I don’t know if I still love him (this is my first relationship). We’re due to start a new rental contract which would tie me in to staying with him for another 6 months. Break up now or stick it out even longer?
