Me (f28) and my partner (m28) have been together for over a year. He was mono before this but interested in exploring. He's found it hard to put himself out there for a few different reasons however so has yet to do anything other than go on a couple of dates with other women.

He told me today he might have a date with a woman from work; she seems keen but idk if that means physical or romantic or what. The only issue I have is that it's someone he works with, but I don't want to knock his confidence.

He has found work difficult for the past year but got a new job and is loving it. He's really happy there and is doing well which has been really amazing. I'm worried that if he gets involved with someone from work that might make things awkward or if things go south that he will start feeling unhappy at work again.

I've always avoiding mixing work with relationships, I really don't think it's a good idea. But I don't want to sound like I'm not happy for him or putting doubt in his mind. I don't know if I should say something or not. And if I do, how best to word it that doesn't make it sound like I'm being a bitch?

He really values my opinion on this sort of stuff, which is great, but I worry I'm going to say the wrong thing. I'm also autistic so wording things properly is not my strong suit, but find it hard not to say my opinion directly.
