Frustrated... Feel like I've lost my best friend.

I have always wanted to be child free. When my best friend of 15 years found out she was pregnant I was one of the last people to find out for fear of my response.

I love her baby & am a very doting aunt. I've babysat him numerous times and have an amazing relationship with him.

He's almost 9 months old now & it's been over a year since I've had a night with just her. It's always me, her & the baby. Or her husband, baby, her & me.

I'm so frustrated... I don't know how to explain to her that sometimes I just need time just the 2 of us. I LOVE her family & I'm grateful to consider myself a part of her family but I don't always enjoy feeling like the odd man out.

I tried to talk to her about it via text ( http://i.imgur.com/xdVvw.png http://i.imgur.com/Ge5TW.png http://i.imgur.com/kFkFw.png ) and feel even more frustrated then before...

Please help me. I don't want to lose my best friend but don't know how much longer I can handle this...

EDIT: posting from phone, sorry if links seem out of order... I'm confused looking at them on here so others might be too...
