what would you choose?

If you're not happy with who you're spending your time with now, would you change? what if you have been with these people for over 2 years.. and it's been great. but just the last couple of months, its seems as if you're not wanted with them anymore? nothing's ever told to you, you're just there. your other friends say to change over to others, but would you? what if you're afraid you will lose those people if you did? what if they forget you? what if you did, and soon you become those small talk friends who just smile at eachother and keep walking? i don't want that. what do i pick?
