Am I misinterpreting things?

[Tippett]

Relatively new acquaintance, friend of friend, decent person who I'm not interested in romantically, and happily he didn't seem interested in me either.

Recently though he told me I had pretty eyes and was attractive and brought me a leaflet on a change coach to help me with something. And phoned a few times today. Would you get worried he was interested? Or am I reading too much into it?

I'm useless at this sort of thing

If he's interested and you're not why are you worried? Just see what happens. I have a similar situation and I'm just not going to encourage anything and they'll get the message, unless of course you are interested!

That's a novel concept. I didn't know if I was being 'vain' by starting to think he's interested (I don't like him in that way).

OK I'll try not to worry and fingers crossed it's nothing, thanks

If you're getting the impression that he is attracted to you, then you are probably right - that's not being "vain" it's just being an adult.

You aren't interested, so
A) maybe rein back on your interactions with him for a bit - don't get drawn into text conversations, don't comment on his stuff on social media (if relevant) if you're both at an event, don't spend all your time with him, etc.

B) in case he does ask you out, practise saying "thanks but no thanks" politely but unambiguously. People (especially female people - I don't know if you are female or not) are raised to be "nice" and put other peoples feelings first, and as such, saying a straightforward "no" can feel unbearably rude. You need to practice saying it, so that it's there for you in the moment you need it.

He might not be romantically interested, but may well be lonely. And you can start to eye up people you don't usually find attractive (or wouldn't want to be in a relationship with) when lonely, I find.

Be cautious, and keep your boundaries up I think.
