I (F21) want to break up with (M22) but I'm not strong enough

This might be long and im sorry. We've been together for almost 2 years now. Things were great at the start. I bsolutely love him and i fell in love with the person who courted me back then. Now that he started working it's like he became so chill about us that he doesn't really put effort into our relationship.

I was a bit clingy and demanding before but I really tried to help myself by reading about how guys want their own space and understanding how their priorities shift towards work and their families especially when they're getting older. Now i'm honestly more mature and okay with that like I don't text him during work, I've accepted that we wont be meeting on weekends because he'll go to his family and have set a time every week where we'll meet each other after his work and have dinner and maybe sex. So that part is okay so far.

However, he never initiates everything. I always end up deciding what we'll do during our date night, I usually text first and ask him if he's home already and I learn that he already is when he should have texted me when he got home. He also usually forgets to reply, especially when he's playing video games or watching stuff. I honestly feel forgotten and I dont feel like im a priority of his. It feels like I'm just part of his routine.

I have talked to him countless times about this and he always says he'll change. He'll plan more stuff he'll surprise me he'll reply etc. Just today we had a fight cause he ignored me again and we sorted it out. But after a while he started not replying again and i was so triggered because we just talked about this and he's doing it again so I tried to break up with him but he pleads me not to. And honestly I really want to stay but I also know that this is bad for me and I dont believe this situation is ever gonna become better. Maybe it could a little but I don't know if itll be enough to get us happy again. And so we had a long talk of me trying to break up and my reasons why and him stopping it although he only says things like dont leave me i love you im sorry, basically things ive heard already from our past fights. Its like a cycle its gonna keep happening and he's gonna say and promise the same things then he'll eventually be back to his old selfish ways of enjoying himself and forgetting about me.

Now I love him so much and I know he does too but theres really just compatibility issues where i want him to be more expressive to me and he cant cause he finds it hard to. He doesn't find texting or chatting that necessary while for me it is because we rarely see each other. There are so many small things that just piled up and got me so hurt and hopeless about us but I cant find the courage to break up with him cause I dont want to regret it and I dont want to endure that kind of pain and importantly cause i love him. He's a great guy and things are okay like most of the time but i just feel like i could be happier. So that's the situation. Ive been adapting to his situation w work and family and time so i feel like this is something that he should be doing for me because im already giving it my all meeting him halfway and truly understanding him. Why cant he do that for me when all i need is constant communication and some affection?

So reddit what should I do? Is breaking up the clear option? Is there something about boys and communication that just really doesnt work? Does starting to work really change people that much and I should understand that? am i too demanding if i want him to reply all the time (i only ask him from this during weekends when he's free at home)

TLDR; i dont know what to do but breaking up is definitely an option. However i'm not strong enough to do it. Help me
