Why do girls change when they get a boyfriend?

melissle
All three of my close friends have become involved in serious relationships in the past year. Apart from the fact that they stopped contacting me (and still don't unless I contact them first), I find that when we hang out, they're not very fun anymore. I noticed this particularly recently with my very best friend of 10 years - she acts very bitter towards me these days and never invites me to go clubbing and doesn't reply to my messages. She always asks her boyfriend and her other friends. And when I ask her to do things, she has excuses like 'not being able to afford it'.

I have to admit, I feel pretty damn hurt and I think about it a lot. Being single, it makes me sad that I've lost 3 good friendships over guys. What happened to having a balance? I have always been so loyal to my friends - I even turned down a date from a guy to see a concert I really wanted to go to because I promised my friends that we'd have a girls night out! Why don't my friends feel the need to reciprocate the loyalty?
