His little sister is older than me..

Is that weird. I always felt he felt some type of way bringing me around his family. I think his sister is one or two years older than me. He’s 26, I’m 20. Maybe I’m just overthinking but by 4 months in other relationships I would have met someone other than the cousin that stays with him... I just feel some type of way.. 😣😕

Please do not bash me.
