Each of us (chooses) our own friends, lovers, and spouse. If we are unhappy with our choice we have a right to make a better choice for ourselves. Only you know if you are unhappy with choice of friends. All relationships are "at will". No one is "stuck" with anyone.
The beautiful thing about a door is it lets those who want in (in) and those who want out (out). We are always where we (choose) to be.
Anyone who is unhappy in a relationship and chooses to stay in it is (choosing) to be unhappy. It's your life! Take the wheel!
