What if I don't want to be second choice?
I'm confused. Can you explain that more to me?
I feel like I'm a total failure in social interactions with other people, so my friends nearly always prefer going out with my friends' girlfriends over me. I feel bad.
You shouldn't settle for second best in relationships. Talk to your friends. Try to be more open and inviting.
I hate accepting the second best. I'll talk to them. I'll try hard to prevent this from happening again.
That's good, keep working on it and I am sure that you will succeed. You don't have to settle for second best in your friendships and relationships.
