No it doesn’t sound “pretty shit” (or “pretty s**t” as you put it – if you’re going to need to censor that out why not just choose a different, and publishable word, you amateur).
Unless of course you’re one seriously clingy little bunny boiler, this is a perfectly rational step a person might take if, for example, they’re not feeling all that mentally well right now, but want to work on that, and then think they would be in a better position afterwards, and can already see they would want to be with the other person, but just not right now.
But oh, no, we see a trendy buzzword to use – it’s FUCKING SHIT TO DO THAT TO SOMEONE!!!! 🙄
