Can you help me draft a nice message to end things?

[Tofupho]

We have been on 6 dates, seeing each other for a month. Not slept together. He is lovely and seems quite into/to see a future, we met on OD by the way.

For context, he is 10 years older and experienced, I am in my twenties and less so. We also have differing work patterns (think two long hours jobs eg lawyer and paramedic with weird shifts), it’s a struggle to see each other but we have been, he in particular has been great at moving things around, I have also done my best.

We are due to see each other next couple of days but as much as I like him, the spark is not really fully there for me. I have been feeling this way the whole time so I think no point dragging it out. I like his company a lot and would be keen to remain friends. Also we have kissed a lot on our dates so I feel like it would be a little disingenuous if I referenced the lack of spark now - just want to be as empathetic as I possibly can really, I’m not used to doing this.

Can anyone help,

Hello, I've really enjoyed the time we've spent together. A romantic relationship with you just isn't for me. Id like a friendship to continue but of course I understand if thats not what you're after. Best wishes

I had a can we be friends message off a bloke last year and we are now friends. Its ok to ask.

I have a bit of a rash so unfortunately our friendship is over. (Not your fault) It's for your own good Dave, we are not suited.
