I don't think I get it...

When one is dating someone are they expected to drop all their other friends? Are they to spend time with other friends only if the significant other is present? Can one never have time with another friend unless their better half is with them?
I don't like dating expectations, sure I understand the obvious ones like no dating other people, no sleeping with other people, spend quality alone time with me etc but I"m not sure I understand the forget everything else that is important to you one.
And you know, I don't think I need to get it. That's just the way I am. Friends are a very close second to anyone I should ever date. I swore I'd never be one of those girls who forgot her friends for the new boy or whatever in her life. And I never will be. I will be sure of that. I"ve been hurt too many times myself from that and I won't do it to those I love.
I mean even better should the person I date be friends with my friends, that's great! But doesn't still mean I won't spend time with friends without them. I've always thought it to be really important that a couple have other friends and aquaintances outside of each other. You can't just be with one person all the time, sure its probably possible but sometimes you just need different company. People who share some of the interests that your significant other doesn't share with you, people who you can talk to you about things that you just can't share with the one you're dating.
Imaing how horrible married life would be if no one had friends or talked with other people other than their husband or wife. Maybe that's why so many marriages are ending. Maybe people are coming to expect too much of their spouse's time and people are just unhappy cause of it...
Also kinda explains why people are saying screw the dating game, I'll stay single or just sleep with random people. It's less complicated, less pressure to be the perfect partner.
