My Друзья are interfering....

It can be quite annoying to have others interfere.

There are times where Ты must be assertive and/or stubborn. Ты need to tell your Друзья (and be persistent about it) that Ты can't always be with them when something happens. Okay, being asked out by someone is a big surprise and everyone wants to celebrate, but do it all on your own times. It's not very necessary when you're with that person; especially when Ты wish to be alone with them.

If they pull that stunt off again ("Okay, I'll leave Ты alo-- OH Эй, DO THIS."), be assertive and say, "I believe Ты сказал(-а) that Ты would let me do things on my own. I would appreciate it if Ты could leave me alone in these situations, thank you." It might sound mean to some, but it's not being aggressive. Being aggressive would be saying something like, "You back off! Don't Ты know how to leave me alone?!" That sounds much worse, doesn't it? Better off to say the first thing than to make bad relations with your friends, trust me.

Explain to that guy-friend of yours that you're sorry about it, and that it -- has been -- beyond your control. Hopefully he'll be able to understand the former dilemma that Ты had, and now things should be different. Your Друзья should learn something too; they aren't the ones who are in control of someone else's life или the decisions that someone else makes. It takes a while to mature, but no one сказал(-а) that some teachings of maturity can't be learned fast. That's why Ты live and learn, and fix the mistakes that you've made before.

Hopefully this helps Ты out. Good luck.
