Unsure if this is working out

Hi reddit! I need some advice from people outside of my personal life just to make sure I’m making the right choice and if I am, how I should approach this.

So I (f20) have been dating a guy (m19) for a little under a month now and I want to end things. I’ve been having a lot of anxiety regarding all of this and I’m not sure how to go about ending things or if it is the right choice.

Here’s why I want to break up:
– He has poor hygiene and I’ve had to tell him ways to take care of himself.
– He leaves my room and personal belongings smelling gross which gives me some sensory issues
– He keeps changing his life goals and opinions to match mine (ex: haircuts, wanting kids or not, where to live in the future, etc)
– Hes making things really serious really fast. He said I love you within a few days of dating and he’s made references at wanting to marry me.
– My last relationship was incredibly abusive (sexually and emotionally) so I can’t have intimacy without shutting down and he sometimes says and does things my abuser did which has been causing some trauma to resurface. (which I had been fine when we started seeing each other)
– I’m constantly driving out to see him and paying for most things, which I think should be a close to 50/50 thing.
– We just don’t have as good of chemistry as he thinks we do.
– Has a really high libido and just isn’t always considerate of the fact that I can’t always handle that mentally and sometimes brings up his horniness right after i’m in a very vulnerable emotional state.

I feel guilty for feeling this way because he is a good person, I just don’t think I want to see him romantically. I’m scared to end things because of his reaction (not because of him, but I have a lot of guilt when it comes to upsetting people and because my last break up was traumatizing.) I wish this would fade away but I would feel awful ghosting him.

I’ve been busy so I’ve had some space away from him to think about this. What should I do?
