Does it matter if friends earn a lot more than you?

[Partyinfrance]

I've been very fortunate to recently make a new group of friends after a lot of bad luck. Only met them a couple of times but it's refreshing to be part of a group where people actually want to see you, rather than too 'busy' for even a coffee once in 10 months (yet out with others)
Anyway the only issue is that they seem to be earning a lot more than me (or at least spending a lot more)
I'm trying to save for a house deposit and to have my first child too. I've found that on the occasions I've been out with them they always went for expensive places and could order several fancy cocktails like they were water. They seem to be able to eat at restaurants every week.
I felt daft going and ordering a small starter and a glass of juice.
I'd like to think these things don't matter, but maybe it does. Even if I had more, I'm just not really a big spender, I'm happy with simple stuff.
So just not sure how to go about it really.. I'd like to keep meeting up with them, I am planning to suggest just a coffee and see how they react, or a walk. Don't want it to cause any issues.
I've had this in the previous group of friends too.

Just an odd thought but have you told them that you can’t afford the meals out? They may genuinely not know.

I have been invited to (what was for me) an extravagantly expensive activity and was taken aback at the invitation because I couldn’t believe that she didn’t realise that it was outside of my spending potential. I still baffle as to how she couldn’t have known but through the years I have subsequently known her I realise that she meant the invitation as genuine and was just being friendly.

She got the gist that those type of activities weren’t for me and she does them with other friends.
