Comparing

So I’ve recently started seeing a guy (let’s call him 1) and he has a twin brother ( call him 2) 2 has a girlfriend. She constantly fights with him about pointless stuff and lately she has been comparing me and 1 to her and 2.

We were at the park with all their mates and 1 sat on my lap. Next minute she was lookin all upset and later went off at 2 saying why doesn’t she sit on his lap. Blah blah and saying “ they do it. Why don’t we?”

And every time 1 holds my hand or hugs me or whatever when she’s around, she looks at us and sorta glares and then goes off her her boyfriend.

I feel uncomfortable now when she’s around if he hugs me because I know she’s gonna use us against her boyfriend and he is such a great guy and shouldn’t have to deal with that
