It can be easy to feel insecure about spending time with friends who are so close to each other, as most twins are, just because they have that close bond with each other and you are naturally excluded from it. That can be awkward, but it doesn't mean that they don't value your friendship. Maybe it would be easier for you to sometimes do things with one of them instead of both together? If you don't have that insecurity in your other relationships, just remember the unique nature of your friendship with these twins and try not to take it personally.
