Hi Ang, both me and my brothers went to single sex schools, and here are my thoughts:

1. Honestly, as a kid I never thought about it. We caught the same bus to and from school, and we were together after school and on weekends. Still very close to my brothers, so I dont think it was detrimental to our relationship at all.

2. I think as a teenage girl, you always feel awkward, no matter who you are around (or was that just me??? ). Just because you go to a singel sex school doesnt mean you dont ever get to interact with the opposite sex. I got to hang out with boys on the bus, waiting for the bus, before and after school. My school also had a brother/sister school we did activities with such as learn to dance, and the formal and also stage productions etc. So plenty of time for interaction!

3. I think it depends on the girls. There are cliques at all girls schools, and at co ed schools. I loved my high school experience, and honestly couldnt imagine what it would be like to go to a co ed school now.

Hope that in some way helps with your decision
