<human>: Can you give me a shortened version of the text?

My GF and I have been dating for 5.5 years and everything is 90% fine but our social standings can make things difficult. She's not very social, shy, not a drinker, has some self confidence issues so making friends is difficult for her and she doesn't really get out to often (high GPA masters student and researcher). I'm also a bit socially awkward but I get along with people and make friends pretty readily, people seem to like me and I keep in contact with a large group of friends. 

The problem is when ever I get invited to go out with friends or something and my GF wasn't explicitly invited she'll get offended when I bring her along as a +1 or something. On the flip side, knowing she has this reaction I sometimes just won't ask her to come and she gets shitty with that too. I don't know what I'm supposed to do to keep my social life and keep her happy, any ideas?
<bot>: GF gets butthurt when she isn't invited to stuff and I bring her as a +1 but also gets upset when I don't take her at all.
