<human>: Hi, I'm just hoping for some advice on how to handle a situation with my best friend. We've both recently turned 18 and have started going out partying. The first time we went out it was just the two of us and it was really fun. The second time we go out she introduces me to her new boyfriend who is nice and easy to get along with. We and some of his friends have a good time out (though we spent half of the night following her boyfriend around like sheep) I pointed out to her that I didn't like this and she although she was shocked she did try to stop following him around. 
The last time I went out with her/them we went to a friend of her boyfriends house for pre drinks before going into town however she left me alone in the house with a bunch of strange guys who I didn't know while she went for a walk with the bf. I got mad and quietly asked her not to do it again. At this point I had a horrible migraine but tried to shake it off however about 12:30am I decided to go home because I felt I was bumming everyone out so I got a taxi home. Now everytime I ask if she is up for going out she says she is already going out with her bf and others and doesn't invite, fair enough. But she has done it 4 times now. I'm starting to think her new friends don't like me because I was ill the last time I was out with them. I'm trying to talk to her about it but she either puts off the convo or ignores me (on facebook) 

I'm starting to feel really insecure.

Can you give me a shortened version of the text?
<bot>: I got ill when me and my best friend were out partying with her new boyfriend and friends and because I went home early I think she's embarrassed by me and doesn't invite me out anymore.
