Hey, I (34m) started seeing a friend (36f) again after we ended things the previous summer. We had been seeing eachother again since this January both with the intention of seeing where it can go this time. Previously between working a job that kept me overworked and burnt out, I admittedly wasn't attentive or communicative (we could go weeks without contact or seeing eachother) she rightfully ended things with me. I genuinely missed her reached out around the new year and we picked back up again, with more contact with eachother and a bit more face time with eachother. Things has been going well, but I've begun to lose those feelings and it's harder for me to prioritize her in my life. As I've gotten to know her more and more, I personally don't feel the strong emotional connection, I feel like there's a disconnect between us, a difference in our values, and how we live out lives, and I'd rather go our separate ways. I feel terrible about this because I had reached out many months ago. I know breaking up is the best option and the right thing to do, however this is my dilemma. I'm genuinely bad at walking away from conversations (something I'm working out with my therapist) I know if I see her and end things there, I'll spend more time defending myself and I will wind up hurting her as I begin to literally choose the wrong words to describe what's going on in my eyes. I fear staying too long and discussing it to a point that I'll either make it worse or back down completely. I'd prefer to text this one in (it's how we ended last time) but, I also feel like that's disrespectful and rude. Which would go against how I feel about her, I still care about her, I just don't feel like we are compatible, and I feel like texting her to end it would just make that sound like bullshit. I could use advice, or at least confirmation of what I'm pretty sure I know is the right thing to do.

Tldr; partner and I, got back together in January after I reached out. I don't feel like we are compatible, I fear breaking up in person will make me back down from my position and i feel like texting is disrespectful. What do?
